description: Despite more than a decade of reform efforts, students continue to experience difficulty understanding and applying statistical concepts. The predominant focus of reform has been on content, pedagogy, technology and assessment, with little attention to instructor characteristics. However, there is strong theoretical and empirical evidence that instructors' attitudes impact the quality of teaching and learning. The objective of this study was to develop and initially validate a scale to measure instructors' attitudes toward reform-oriented (or concept-based) teaching of introductory statistics in the health and behavioral sciences, at the tertiary level. This scale will be referred to as FATS (Faculty Attitudes Toward Statistics). Data were obtained from 227 instructors (USA and international), and analyzed using factor analysis, multidimensional scaling and hierarchical cluster analysis. The overall scale consists of five sub-scales with a total of 25 items, and an overall alpha of 0.89. Construct validity was established. Specifically, the overall scale, and subscales (except perceived difficulty) plausibly differentiated between low-reform and high-reform practice instructors. Statistically significant differences in attitude were observed with respect to age, but not gender, employment status, membership status in professional organizations, ethnicity, highest academic qualification, and degree concentration. This scale can be considered a reliable and valid measure of instructors' attitudes toward reform-oriented (concept-based or constructivist) teaching of introductory statistics in the health and behavioral sciences at the tertiary level. These five dimensions influence instructors' attitudes. Additional studies are required to confirm these structural and psychometric properties.

Quadrilateri in narrazione: un percorso integrato di matematica e narrazione

description: Le discipline di matematica e italiano ricoprono un ruolo cardine nel contesto scolastico ticinese e quasi sempre vengono trattate in modo separato. Di recente si sta facendo strada una visione che intende favorire un approccio metodologico incline a legare maggiormente le due materie con possibili effetti positivi su entrambe. Ciò potrebbe aiutare gli allievi a sviluppare anche competenze trasversali. Con la presente ricerca, sperimentata in una IV elementare, si è indagata la capacità di integrare aspetti geometrici, in particolare legati ai quadrilateri, in un testo narrativo creato dagli allievi. I risultati sono stati raccolti prima e dopo una serie di interventi didattici sulla tipologia testuale narrativa e sui quadrilateri. L’analisi dei dati dimostra che inizialmente i bambini sono riusciti a produrre un racconto che contiene enti geometrici ma non le relative proprietà; dopo il percorso didattico realizzato alcuni di loro sono stati in grado di rendere le proprietà dei personaggi geometrici l’anima della storia. È possibile che il progresso registrato sia dipeso in parte dalla messa a disposizione di strumenti funzionali a una pianificazione preventiva della narrazione. Una consegna di questo tipo pone l’allievo al centro del proprio processo di apprendimento, poiché invitato ad agire in modo attivo su concetti geometrici e linguistici elaborati in classe.

description: Elsinoë fawcettii and E. australis are necrotrophic fungal pathogens which cause citrus scab and sweet orange scab, respectively. E. fawcettii causes disease on a wide range of citrus varieties around the world, while E. australis causes disease on sweet orange in South America. Recently, novel pathotypes of E. australis have been identified in Australia, including the Jojoba Black Scab (JBS) pathotype which causes black scab disease on jojoba and the Finger Lime (FL) pathotype which causes disease on finger lime fruit. As citrus is an economically important crop in Australia, research into pathogens of citrus and closely related pathogens is needed. It is known that species of Elsinoë produce elsinochrome, a secondary metabolite which contributes towards virulence in a non-host selective manner. However, the pathogen-host processes occurring before the release of elsinochrome are not understood, yet host-specificity is well known among the species and pathotypes suggesting such processes occur. This study produced genome assemblies for two species of Elsinoë, including four E. fawcettii (25.8 – 26.4 Mb), four E. australis JBS pathotype (26.6 Mb) and one E. australis FL pathotype (23.8 Mb). Phylogenetic analyses were conducted indicating the E. fawcettii pathotypes were very closely related, while the E. australis pathotypes were distinct from one another. Genome mining for pathogenicity related genes indicated that Elsinoë have a repertoire of predicted candidates including five secondary metabolite gene clusters, in addition to elsinochrome, that are conserved among Elsinoë, as well as 186 - 219 cell wall degrading enzymes and 94 – 120 prioritised effectors which may be enabling their host-specific pathogenesis pathways. Comparative analyses with other Elsinoë and with other fungal plant pathogens (Botrytis cinerea, Parastagonospora nodorum, Pyrenophora tritici-repentis, Sclerotinia sclerotiorum, Zymoseptoria tritici, Leptosphaeria maculans, Pyricularia oryzae (syn. Magnaporthe oryzae), Rhynchosporium commune, Verticillium dahliae and Ustilago maydis) assisted with the shortlisting of candidate effectors. Genomic regions of potential plasticity were also identified, indicating predicted virulence related genes of some Elsinoë, such as candidate effectors, were more likely to be located in the close vicinity of transposable elements and adenine and thymine (AT)-rich regions. This provides an insight into the potential maintenance of pathogenicity-related genes of Elsinoë, in addition it highlights regions of the genome which may hold further virulence factors not predicted by current methods. This study has established a comprehensive resource for future experimental validation of genes which Elsinoë utilise in order to infect plants in a host selective manner.

description: Theories for new particle and early-Universe physics abound with pseudo-Nambu-Goldstone fields that arise when global symmetries are spontaneously broken. The coupling of these fields to the Chern-Simons term of electromagnetism may give rise to cosmological birefringence (CB), a frequency-independent rotation of the linear polarization of photons as they propagate over cosmological distances. Inhomogeneities in the CB-inducing field may yield a rotation angle that varies across the sky. Here we note that such a spatially-varying birefringence may be correlated with the cosmic microwave background (CMB) temperature. We describe quintessence scenarios where this cross-correlation exists and other scenarios where the scalar field is simply a massless spectator field, in which case the cross-correlation does not exist. We discuss how the cross-correlation between CB-rotation angle and CMB temperature may be measured with CMB polarization. This measurement may improve the sensitivity to the CB signal, and it can help discriminate between different models of CB.

On the Anomalous Radii of the Transiting Extrasolar Planets

description: We present a systematic evaluation of the agreement between the observed radii of 90 well-characterized transiting extrasolar giant planets and their corresponding model radii. Our model radii are drawn from previously published calculations of core-less giant planets that have attained their asymptotic radii, and which have been tabulated for a range of planet masses and equilibrium temperatures. (We report a two-dimensional polynomial fitting function that accurately represents the models). As expected, the model radii provide a statistically significant improvement over a null hypothesis that the sizes of giant planets are completely independent of mass and effective temperature. As is well known, however, fiducial models provide an insufficient explanation; the planetary radius anomalies are strongly correlated with planetary equilibrium temperature. We find that the radius anomalies have a best-fit dependence, ${\cal R}\propto T_{\rm eff}^α$, with $α=1.4\pm0.6$. Incorporating this relation into the model radii leads to substantially less scatter in the radius correlation. The extra temperature dependence represents an important constraint on theoretical models for Hot Jupiters. Using simple scaling arguments, we find support for the hypothesis of Batygin and Stevenson (2010) that this correlation can be attributed to a planetary heating mechanism that is mediated by magnetohydrodynamic coupling between the planetary magnetic field and near-surface flow that is accompanied by ohmic dissipation at adiabatic depth. Additionally, we find that the temperature dependence is likely too strong to admit kinetic heating as the primary source of anomalous energy generation within the majority of the observed transiting planets.

description: We give a complete characterization for pure quantum measurements, i.e., for POVMs which are extremals in the convex set of all POVMs. Such measurements are free from classical noise. The characterization is valid both in discrete and continuous cases, and also in the case of an infinite Hilbert space. We show that sharp measurements are clean, i.e. they cannot be irreversibly connected to another POVMs via quantum channels and thus they are free from any additional quantum noise. We exhibit an example which demonstrates that this result could also be approximately true for pure measurements.

description: We place constraints on the average density (Omega_m) and clustering amplitude (sigma_8) of matter using a combination of two measurements from the Sloan Digital Sky Survey: the galaxy two-point correlation function, w_p, and the mass-to-galaxy-number ratio within galaxy clusters, M/N, analogous to cluster M/L ratios. Our w_p measurements are obtained from DR7 while the sample of clusters is the maxBCG sample, with cluster masses derived from weak gravitational lensing. We construct non-linear galaxy bias models using the Halo Occupation Distribution (HOD) to fit both w_p and M/N for different cosmological parameters. HOD models that match the same two-point clustering predict different numbers of galaxies in massive halos when Omega_m or sigma_8 is varied, thereby breaking the degeneracy between cosmology and bias. We demonstrate that this technique yields constraints that are consistent and competitive with current results from cluster abundance studies, even though this technique does not use abundance information. Using w_p and M/N alone, we find Omega_m^0.5*sigma_8=0.465+/-0.026, with individual constraints of Omega_m=0.29+/-0.03 and sigma_8=0.85+/-0.06. Combined with current CMB data, these constraints are Omega_m=0.290+/-0.016 and sigma_8=0.826+/-0.020. All errors are 1-sigma. The systematic uncertainties that the M/N technique are most sensitive to are the amplitude of the bias function of dark matter halos and the possibility of redshift evolution between the SDSS Main sample and the maxBCG sample. Our derived constraints are insensitive to the current level of uncertainties in the halo mass function and in the mass-richness relation of clusters and its scatter, making the M/N technique complementary to cluster abundances as a method for constraining cosmology with future galaxy surveys.

Development of an in-situ detector for dissolved gases in liquid waste

Publisher: name: University of British Columbia

description: Monitoring volatile compounds in sewer systems is highly important due to the toxic and corrosive nature of various nuisance chemicals generated, such as hydrogen sulfide (H₂S). Hotspot monitoring facilitates identification of the location of the generated H₂S, and thereby targeted treatment can be applied, which eventually minimizes the use of chemicals and lowers the environmental effect within the sewer system. In this thesis, we present a portable detector that is designed to extract volatile components from aqueous samples by vaporizing the sample and then exposing it to a microfluidic-based detector, fabricated by a selective microchannel embedded with a metal oxide semiconductor (MOS) sensor. The setup consists of an exposure and recovery chamber, heater, servo, and a peristaltic liquid pump. The entire device is controlled using a microcomputer that transmits sensor data and receives inputs from the user. A testing procedure is also established for the setup, which consists of 5 steps, including sample extraction, vaporization, exposure, recovery, and purging. Using a wide concentration ranges of H₂S and ammonia (NH₃) dissolved in water (i.e., two components which the MOS sensor has potential cross-selectivity), a database for classification and regression was developed: the device was capable of classifying between NH₃ and H₂S by a recall value of 100% and 96% in separate and also returned a recall value of 97% with H₂S classification and 96% with NH3 classification in mixture aqueous solutions. Regression precision for separate and mixture aqueous solutions was 84.6% and 88.77%, respectively. The developed setup was used in a field test (at Annacis Island (Delta, BC) wastewater treatment plant (AI-WWTP)) where various tasks such as sample extraction, evaporation, and data transmission were automatically performed. The results show that the device is capable of identifying and measuring the concentration of H₂S and NH₃ in raw influent with 83.48% precision. Overall, the results presented show the potential of the proposed automated wireless device in recognizing and measuring NH₃ and H₂S in sewer systems which can facilitate the detection of hotspots, reduction of treatment costs, increase of the lifespan of buried infrastructure, and minimization of the involvement of highly-skilled personnel.

description: This thesis investigates the use of problem-specific knowledge to enhance a genetic algorithm approach to multiple-choice optimisation problems.It shows that such information can significantly enhance performance, but that the choice of information and the way it is included are important factors for success.Two multiple-choice problems are considered.The first is constructing a feasible nurse roster that considers as many requests as possible.In the second problem, shops are allocated to locations in a mall subject to constraints and maximising the overall income.Genetic algorithms are chosen for their well-known robustness and ability to solve large and complex discrete optimisation problems.However, a survey of the literature reveals room for further research into generic ways to include constraints into a genetic algorithm framework.Hence, the main theme of this work is to balance feasibility and cost of solutions.In particular, co-operative co-evolution with hierarchical sub-populations, problem structure exploiting repair schemes and indirect genetic algorithms with self-adjusting decoder functions are identified as promising approaches.The research starts by applying standard genetic algorithms to the problems and explaining the failure of such approaches due to epistasis.To overcome this, problem-specific information is added in a variety of ways, some of which are designed to increase the number of feasible solutions found whilst others are intended to improve the quality of such solutions.As well as a theoretical discussion as to the underlying reasons for using each operator,extensive computational experiments are carried out on a variety of data.These show that the indirect approach relies less on problem structure and hence is easier to implement and superior in solution quality.

description: The concept of the "Kondo box" describes a single spin, antiferromagnetically coupled to a quantum dot with a finite level spacing. Here, a Kondo box is formed in a carbon nanotube interacting with a localized electron. We investigate the spins of its first few eigenstates and compare them to a recent theory. In an 'open' Kondo-box, strongly coupled to the leads, we observe a non-monotonic temperature dependence of the nanotube conductance, which results from a competition between the Kondo-box singlet and the 'conventional' Kondo state that couples the nanotube to the leads.

description: Physical modeling studies have endeavored to quantify the influence of plant biophysical parameters and hydrodynamics on wave-vegetation interactions and coastal protection. The accuracy with which such studies have characterized stem motion is limited by the predominant use of plant surrogates, and the few saltmarsh species considered in live vegetation studies. To address this, prototype-scale experiments were conducted in the outdoor Large Wave Canal of the Institut National de la Recherche Scientifique, Québec, in collaboration with the University of Ottawa and the National Research Council Canada, allowing novel characterization of live vegetation deformation under wave action. Two saltmarsh species were investigated (Spartina alterniflora, Spartina patens) under various irregular wave conditions (0.03 m< Hs <0.28 m, Ts ≈ 2.5, 10 s). Stem deformation was characterized using submerged cameras and bending angle tracking, coupled with wave height and velocity measurements. Significant differences in stem flexibility were observed between species, with S. alterniflora exhibiting more rigid stems (EIalterniflora=0.051 Nm2) than S. patens (EIpatens=0.0015 Nm2; t-test; p<0.05). The two species consequexhibited different bending angles under similar hydrodynamic conditions, expected to influence their relative coastal protection capacity. These findings provide critical insight into the design of marsh construction or restoration for coastal protection.

Layers of complexity: the importance of realism in neural network classifications of interacting galaxies

description: Visual classification is hard. It is time-consuming and ultimately subjective. Fortunately, there are solutions to these problems in the form of citizen science projects and machine learning methods. But far more challenging is identification and classification of interacting systems. When armed only with photometry, contaminants such as field stars and unfortuitously projected galaxies often lead to misclassifications (dependence on environment). Similarly, the classifcations rely sensitively on the identification of low-surface brightness features such as tidal arms, streams, and shells (dependence on sky brightness and resolution). Simulations, on the other hand, offer foreknowledge of the stage of an interaction. Using a suite of 24 galaxy interactions covering a range of mass ratios and orbits with corresponding secular evolution runs, we train convolutional neural networks to classify galaxies into three categories: (iso) isolated; (p/i) pair/interacting; and (pm) post-merger. Our networks are trained on images with increasing levels of realism: (0) projected stellar mass maps; (1) full radiative transfer; (2) insertion into real images. We are then well-poised to answer unique questions. How important is the level of realism to the successful classification of interacting systems? How important is it to train the network with contaminating effects (inserting into real images) so that the network may adequately discriminate between bona-fide interactions and false positives? In this talk, I will discuss our answers to these questions.

description: Understanding the cosmic re-ionization is one of the key goals of the modern observational cosmology. High redshift QSO spectra can be used as background light sources to measure absorption by intervening neutral hydrogen. We investigate neutral hydrogen absorption in a deep, moderate-resolution Keck/Deimos spectrum of QSO CFHQSJ2329-0301 at z=6.4. This QSO is one of the highest redshift QSOs presently known at z=6.4 but is 2.5 mag fainter than a previously well-studied QSO SDSSJ1148+5251 at z=6.4. Therefore, it has a smaller Stromgren sphere, and allows us to probe the highest redshift hydrogen absorption to date. The average transmitted flux at 5.9154.9. These results are consistent with strong evolution of the optical depth at z>5.7.

description: La peculiarità dell’edificio è quella di sorgere su un terreno scosceso. L’obiettivo è quindi quello di garantire stabilità all’edificio, ma di mantenere anche le facciate libere e gli spazi interni come disposti dall’architetto. La facciata, dovrà essere ventilata, rivestita in pannelli di legno. L'opera occuperà circa 70 m2, rispetto la superficie totale di 1285 m2. Questo perché, la superficie non occupata, considera l'edificio già esistente ed il terreno circostante. L’edificio dovrà essere totalmente comunicante con l’abitazione già esistente. Il passaggio tra i due edifici infatti, permetterà la comunicazione tra i vari piani dell’abitazione da realizzare.
The effect of cure cycle on microstructure and mechanical properties of interlayer toughened composites
Creators: name: Chen, Cheng
Publisher: name: University of British Columbia

description: Carbon fibre reinforced thermoset composites make for lighter and stronger structures and are widely used for secondary and primary structures of commercial airplanes. The cure cycle is important to achieve a high quality of composite components. Cure path dependency for thermoset composites has received increasing interest from automotive and aerospace researchers as fast cure cycles are required to achieve high-volume and low-cost composites manufacturing. Furthermore, toughened composites are using increasingly complex resin formulations and laminate microstructures to increase fracture and damage resistance. These advances raise the question whether modifying the cure cycle affects microstructures and chemical, physical and mechanical properties of toughened composites. This dissertation studies the processing-microstructure-property relationship for the interlayer toughened thermoset prepreg composite T800SC/3900-2B. The work has three main parts. The first part investigates curing effects on interlaminar microstructure and properties of composite constituents. Laminates were processed to the same degree of cure using different cure cycles. Interlaminar microstructure and particle morphology were examined using optical microscopy and scanning electron microscopy. In-situ elastic modulus of the base resin and toughening particles was characterized using nanoindentation. The second part studies curing effects on elastic properties during cure. Lamina shear modulus development was measured using dynamic mechanical analysis. The third part investigates curing effects on mechanical properties after complete cure. Mode I and Mode II interlaminar fracture toughness were measured using double cantilever beam and end-notched flexure tests. Damage resistance was examined using quasi-static indentation and low-velocity impact test. The work revealed that cure path dependency for T800SC/3900-2B prepreg composites is mainly driven by the glass transition of interlaminar toughening particles. Microstructural characteristics such as the interlayer thickness, particle shape and particle volume fraction, and manufacturing anomalies such as fibre migration into the interlayer, are affected by particle deformation which is dependent on the material state of particles in the pre-gelation stage. Cure-dependent interlaminar microstructures affect both elastic properties during cure and mechanical properties after complete cure. This dissertation discovered a new mechanism for cure path dependency of interlayer toughened composites, glass transition of the toughening particles, which is governed by the cure path in a conversion-temperature-transformation process map.

description: Water-rich super-Earth exoplanets are expected to be common. We explore the effect of late giant impacts on the final bulk abundance of water in such planets. We present the results from smoothed particle hydrodynamics simulations of impacts between differentiated water(ice)-rock planets with masses between 0.5 and 5 M_Earth and projectile to target mass ratios from 1:1 to 1:4. We find that giant impacts between bodies of similar composition never decrease the bulk density of the target planet. If the commonly assumed maximum water fraction of 75wt% for bodies forming beyond the snow line is correct, giant impacts between similar composition bodies cannot serve as a mechanism for increasing the water fraction. Target planets either accrete materials in the same proportion, leaving the water fraction unchanged, or lose material from the water mantle, decreasing the water fraction. The criteria for catastrophic disruption of water-rock planets are similar to those found in previous work on super-Earths of terrestrial composition. Changes in bulk composition for giant impacts onto differentiated bodies of any composition (water-rock or rock-iron) are described by the same equations. These general laws can be incorporated into future N-body calculations of planet formation to track changes in composition from giant impacts.

description: The di-fermion angular distribution observed in decays of inclusively produced vector particles is characterized by two frame-independent observables, reflecting the average spin-alignment of the produced particle and the magnitude of parity violation in the decay. The existence of these observables derives from the rotational properties of angular momentum eigenstates and is a completely general result, valid for any J=1 state and independent of the production process. Rotation-invariant formulations of polarization and of the decay parity-asymmetry can provide more significant measurements than the commonly used frame-dependent definitions, also improving the quality of the comparisons between the measurements and the theoretical calculations.

description: Phylloplane yeasts are an important part of microbial communities in tropical and temperate regions. In Australia, the diversity of phylloplane yeasts on crops and indigenous plant species has received little attention. The aim of this study was to isolate and identify phylloplane yeasts from Banksia integrifolia in south-eastern Queensland. This study showed that leaves of B. integrifolia harboured a high diversity of yeasts, including putatively novel species in Bannoa, Hannaella and Vishniacozyma. Further, several phylloplane yeast species found on B. integrifolia in south-eastern Queensland had not been previously reported from Australia. Banksia integrifolia is an iconic native Australian tree, which is widespread throughout coastal heathlands from Tasmania to southern Queensland. Leaves of B. integrifolia at different canopy heights were collected from undisturbed ecosystems at three locations in south-eastern Queensland. Phylloplane yeasts were isolated, cultured and preserved for morphological, physiological and molecular examination. DNA of the yeast was extracted, amplified and their sequences analysed by comparison with the sequences of reference isolates in GenBank. Molecular phylogenetic analyses showed that most of the yeasts belonged to basidiomycetous genera, especially Bannoa, Hannaella and Vishniacozyma. Five putative novel species were identified from Bannoa, Hannaella, and Vishniacozyma. This study shows that B. integrifolia has a rich diversity of phylloplane yeast species, including some that are apparently endemic to Australia.

Clues on radio AGN feedback at high-redshift from deep radio surveys

Year: 2019

description: We examined one of the largest and most complete sample of non-local radio Active Galactic Nuclei (AGN) to-date, which are key laboratories for exploring the role of supermassive black hole (SMBH) feedback in shaping the evolution of galaxies. The question we tried to address is: "Does radio AGN feedback follow or quench galaxy star formation across cosmic time?" The VLA-COSMOS 3 GHz Large Project (PI: Smolcic) is the deepest radio-continuum survey of the high-z Universe, and thus provides a unique view of the radio faint AGN population at 0.61200 radio AGN that is complete in radio luminosity at various redshifts. We observed that the fraction of radio AGN hosted by star-forming (SF) galaxies increases with redshift, at fixed Lr. Interestingly, also the average SMBH accretion rate (measured from deep X-ray data) evolves in a strikingly similar fashion, implying a persistent link between AGN and galaxy growth. Intriguingly, the same fractions of SF hosts are also shown by a control sample (matched in redshift and stellar mass) of non-radio-AGN, at all redshifts, as if the presence of a radio AGN did not affect the evolution of galaxies' SF content. Our results suggest that: (1) Radio AGN show widespread SMBH accretion and star formation towards higher redshifts; (2) radio AGN feedback might not be the primary culprit for quenching galaxy star formation. I will discuss the implications of this study into a broad framework of AGN/galaxy evolution.
Zero temperature geometric spin dephasing on a ring in presence of an Ohmic environment

description: We study zero temperature spin dynamics of a particle confined to a ring in presence of spin orbit coupling and Ohmic electromagnetic fluctuations. We show that the dynamics of the angular position $θ(t)$ are decoupled from the spin dynamics and that the latter is mapped to certain correlations of a spinless particle. We find that the spin correlations in the $z$ direction (perpendicular to the ring) are finite at long times, i.e. do not dephase. The parallel (in plane) components for spin $\half$ do not dephase at weak dissipation but they probably decay as a power law with time at strong dissipation.

An approach for the calculation of one-loop effective actions, vacuum energies, and spectral counting functions

Year: 2010
Subjects: subject: High Energy Physics - Theory (hep-th)

description: In this paper, we provide an approach for the calculation of one-loop effective actions, vacuum energies, and spectral counting functions and discuss the application of this approach in some physical problems. Concretely, we construct the equations for these three quantities; this allows us to achieve them by directly solving equations. In order to construct the equations, we introduce shifted local one-loop effective actions, shifted local vacuum energies, and local spectral counting functions. We solve the equations of one-loop effective actions, vacuum energies, and spectral counting functions for free massive scalar fields in $\mathbb{R}^{n}$, scalar fields in three-dimensional hyperbolic space $H_{3}$ (the Euclidean Anti-de Sitter space $AdS_{3}$), in $H_{3}/Z$ (the geometry of the Euclidean BTZ black hole), and in $S^{1}$, and the Higgs model in a $(1+1)$-dimensional finite interval. Moreover, in the above cases, we also calculate the spectra from the counting functions. Besides exact solutions, we give a general discussion on approximate solutions and construct the general series expansion for one-loop effective actions, vacuum energies, and spectral counting functions. In doing this, we encounter divergences. In order to remove the divergences, renormalization procedures are used. In this approach, these three physical quantities are regarded as spectral functions in the spectral problem.

Electron density in different environments at redshift 1.6
Creators: name: Harshan, Anishya

Publisher: name: Zenodo
Year: 2019

description: The star formation rates for galaxies in early universe (z >1.0) is observed to be 10 times higher than galaxies in the low redshift (z<0.5) regime. In addition to the SFRs, the conditions of star formation are also found different at high and low redshift regimes and in different environments. To understand what is driving this evolution in star formation rates, and thus the evolution of galaxies, we need to understand the physical conditions such as the electron density of these star forming regions. In this talk, I will present my work on the electron density in a z = 1.6 galaxy cluster. Our results show a systematic increase in electron density in cluster environments than field environments which is in contrast to previous studies.
