Gas dynamics across cosmic time
Creators: name: Lelli, Federico
Publisher: name: Zenodo
Year: 2021

description: The emission lines of cold/warm gas are key tools to trace galaxy dynamics at different cosmic epochs. At z=0, the combination of Hα, CO, and HI observations allowed studying gas dynamics in hundreds of galaxies of different masses and morphologies, from quiescent ellipticals to star-forming dwarf irregulars. Regular rotation and low gas turbulence are the rule at z=0 with the exception of interacting and merging systems. Combined Hα+HI rotation curves extend from the innermost regions of galaxies out to tens of effective radii, probing deep into their dark matter halos. These data revealed surprisingly tight scaling relations between baryons and dark matter, which challenge current models of galaxy formation. At z=1-3, integral-field spectroscopy of Hα and [OIII]5007 Å lines allowed tracing the inner dynamics of massive galaxies for significant samples: the importance of disk turbulence, the rotation-curve shapes, and the evolution of scaling relations remain debated at this cosmic epoch. Radio and sub-mm interferometry of CO and [CI] lines are also key tools at z=1-3 albeit currently limited to small galaxy samples. At z=4-7, ALMA observations of the [CII]-158 μm line have opened anm line have opened an entirely new window for galaxy dynamics. The study of the high-z Universe is particularly promising to test the predictions of current models of galaxy formation.

Recent Developments in Magnetic Dynamo Theory

subject: FOS: Physical sciences

description: Some recent results and open issues in magnetic dynamo theory are addressed. The distinction between small-scale and mean-field dynamo (MFD) action in forced turbulent flows is emphasized. Though useful, the MFD has been controversial. This is partly due to concerns about its need for helically forced turbulence, but mainly because simple "textbook" treatments are kinematic and linear. The non-linear backreaction of the growing magnetic field has been suspected to prematurely quench MFD action. To resolve the controversy, we must first understand those non-linear MFDs which can be numerically simulated. Recently, there has been progress on this front. For simple MFDs in closed systems, dynamical quenching models that incorporate a transfer of magnetic helicity between small and large scales agree reasonably well with fully 3-D numerical periodic box simulations. Unresolved issues such as the quenching of turbulent diffusion and the additional physics needed to apply these results to real systems are also discussed herein. The following summarizes conceptual progress in describing mean-field magnetic energy growth in the simplest MFDs: For a closed turbulent flow, the non-linear mean-field dynamo, is first fast and kinematic, then slow and dynamic, and magnetic helicity transfer makes it so.

Si bien tiene un avance crítico alrededor del concepto con nuevos aportes epistemológicos, las nociones al respecto en zonas periféricas como el Caribe se conciben como herencias terminológicas y que no corresponden a la esencia particular de los contextos y realidades. En ese sentido, surge la necesidad de generación de un conocimiento propio referente a la Geopolítica desde el Caribe en vez de hacia el Caribe.

description: MRSA, a resistant bacteria causing severe infections, is targeted by researchers developing new anti-resistance compounds. The study aimed to investigate the MRSA inhibitory activity of two series of benzofuran-pyrazolo[1,5-a]pyrimidines 1 and 2, attached to arene units via methylene or azo linkage, respectively. The desired products were prepared, in 82–92% yields, by reacting benzofuran-based enaminone 4 with the appropriate 1H-pyrazole-3,5-diamines 5 in pyridine at reflux for 5–6 h. The new hybrids showed a wide spectrum of antibacterial activity against different ATCC strains. Products with azo linkage and para-substituted arene units with electron-releasing groups demonstrated higher antibacterial activity. 3-((4-Methoxyphenyl)diazenyl)-linked pyrazolo[1,5-a]pyrimidine 2e demonstrates activity that exceeded the reference ciprofloxacin with MIC/MBC values of 1.8/3.6 µM against S. aureus and E. coli strains. Also, it demonstrated more effective MRSA inhibitory activity than the reference linezolid, with MIC/MBC values of 3.6/14.4 and 1.8/7.2 µM against MRSA ATCC:33591 and ATCC:43300 strains, respectively.

 Megalographa culminicola Barbut and Piñas 2007: 19. Holotype: male, MNHN, Paris [photographs examined]; Type locality: Carchi, Impuera, Ecuador.
 Diagnosis. This species is an anomaly. The forewing pattern is unlike any other species of Megalographa, whereas the genitalia appear to be indistinguishable from those of M. agualaniata. The species can easily be recognized within Megalographa by the elongated, narrow, tapering stigma, not the usually bilobed or two-lobed stigma of the other species in the genus. The sexes are similar. The male genitalia are like those of M. agualaniata (Fig. 10), but the uncus is slightly stouter and the mesial bulge in the vesica is positioned closer to the base because the basal part of the vesica is much shorter in M. culminicola.
 Distribution and Habitat. Megalographa culminicola occurs in the páramo zone, 3300–3940 m, high in the Andes in Ecuador and northern Peru.

description: This article concerns the nonparametric Fisher–Pitman tests for paired replicates and independent samples. After outlining the theory of exact tests, I derive Monte Carlo simulations for both of them. Simulations can be useful if one deals with many observations because of the complexity of the algorithms in regard to sample sizes. The tests are designed to be a more powerful alternative to the Wilcoxon signed-rank test and the Wilcoxon–Mann–Whitney rank-sum test if the observations are given on at least an interval scale. The results gained by Monte Carlo versions of the tests are accurate enough in comparison to the exact versions. Finally, I give examples for using both supplemented tests.

description: A new series of 1,2,3-triazole skeleton incorporated pyrrole derivatives (11a–j) were developed and their chemical structures were confirmed by analytical data. Further, the anticancer profile of these newly derived compounds 11a–j was assessed against four types of human cancer cell lines such as human breast cancer (MCF-7), lung cancer (A549), colon cancer (Colo-205) and ovarian cancer (A2780) by employing of the MTT method and was compared with etoposide used as a positive control. Most of the examined derivatives displayed moderate to good activity compared with the positive control. Among them, five compounds 11a, 11b, 11c, 11d, and 11e showed more potent activity. Particularly, compound 11a showed superior activity.

description: The 1998 September outburst of the black-hole X-ray binary XTE J1550-564 was monitored at X-ray, optical and radio wavelengths. We divide the outburst sequence into five phases and discuss their multiwavelength properties. The outburst starts with a hard X-ray spike, while the soft X-ray flux rises with a longer timescale. We suggest that the onset of the outburst is determined by an increased mass transfer rate from the companion star, but the outburst morphology is determined by the distribution of specific angular momentum in the accreting matter. The companion in XTE J1550-564 is likely to be an active magnetic star, with a surface field strong enough to influence the dynamics of mass transfer. We suggest that its magnetic field can create a magnetic bag capable of confining gas inside the Roche lobe of the primary. The impulsive rise in the hard X-rays is explained by the inflow of material with low angular momentum onto the black hole, on a free-fall timescale, when the magnetic confinement breaks down. At the same time, high angular momentum matter, transferred via ordinary Roche-lobe overflow, is responsible for the formation of a disk.

description: The Fornax cluster is one of the closest dense environments where earlytype galaxy evolution can be studied in great detail. It has been subject to several spectroscopic surveys, dedicated to disentangle the assembly history of its member galaxies and to characterise the properties of small stellar systems. In the core of Fornax, more than 2500 radial velocities of globular clusters (GCs) and ultra-compact dwarf galaxies (UCDs) as well as ~1500 of planetary nebulae (PNe) have been collected from surveys with different instruments (FORS, VIMOS, FLAMES, MUSE). They were used to study the complex kinematic structure in the cluster core. The flat velocity dispersion profile beyond 50 kpc from NGC 1399 can be explained by a superposition of the central galaxy and cluster potentials, with contributions from stellar streams that trace interaction events. I will present recent results on our understanding of the assembly of the Fornax cluster core, based on this large spectroscopic dataset.

description: Topological states of quantum matter have inspired both fascinating physics findings and exciting opportunities for applications. Due to the over-complicated structure of, as well as interactions between, real materials, a faithful quantum simulation of topological matter is very important in deepening our understanding of these states. This requirement puts the quantum superconducting circuits system as a good option for mimicking topological materials, owing to their flexible tunability and fine controllability. As a typical example herein, we realize a $\mathbb{Z}_2$-type topological insulator featuring the quantum spin Hall effect state, using a coupled system of transmission-line resonators and transmons. The single-excitation eigenstates of each unit cell are used as a pseudo-spin 1/2 system. The boundary of the topological phase transition is fixed in the phase diagram. Topological edge states are shown, which can be experimentally verified by detecting the population at the boundary of the plane. Compared to the previous simulations, this compositional system is fairly controllable, stable and less limited. Therefore, our scheme provides a reliable platform for faithful quantum simulations of topological matter.

description: In an endeavor to invent new antimalarial and antimicrobial agents, a series of coumarin bound 1,4-disubstituted 1,2,3-triazoles was synthesized through Cu(I)-promoted click reaction between coumarin bound terminal alkynes, that is, 4/7-(prop-2-yn-1-yloxy)-2H-chromen-2-one and 2-azido-N-arylpropanamides. The synthesized 1,2,3-triazoles were characterized by FTIR,1H NMR,13C NMR, and HRMS techniques and were assessed for in vitro antimalarial activity against Plasmodium falciparum as well as in vitro antimicrobial activity against four bacterial strains (Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Klebsiella pneumoniae) and two fungal strains (Candida albicans, Aspergillus niger). Compound 7o [(N-(4-fluorophenyl)-2-(4-(((2-oxo-2H-chromen-7-yl)oxy)methyl)-1H-1,2,3-triazol-1-yl)propanamide)] displayed better activity against P. falciparum while compound 7y [(N-(3-nitrophenyl)-2-(4-(((2-oxo-2H-chromen-7-yl)oxy)methyl)-1H-1,2,3-triazol-1-yl)propanamide)] displayed excellent activity against all the tested bacterial and fungal strains, amongst the synthesized triazoles. Also, the molecular docking studies of the most potent compounds against DNA gyrase (S. aureus) were also performed to have an insight on binding interactions.

description: Stem-and-leaf displays have been widely taught since John W. Tukey publicized them energetically in the 1970s. They remain useful for many distributions of small or modest size, especially for showing fine structure such as digit preference. Stata’s implementation stem produces typed text displays and has some inevitable limitations, especially for comparison of two or more displays. One can re-create stem-and-leaf displays with a few basic Stata commands as scatterplots of stem variable versus position on line with leaves shown as marker labels. Comparison of displays then becomes easy and natural using scatter, by(). Back-to-back presentation of paired displays is also possible. I discuss variants on standard stem-and-leaf displays in which each distinct value is a stem, each distinct value is its own leaf, or axes are swapped. The problem shows how one can, with a few lines of Stata, often produce standard graph forms from first principles, allowing in turn new variants. I also present a new program, stemplot, as a convenience tool.

description: We have obtained infrared photometry for the soft x-ray transient GU Mus. We present J and K_s band light curves modeled with WD98, the newest version of the Wilson-Devinney light curve modeling code. Using detailed models for the expected ellipsoidal variations due to the non-spherical secondary star, we show that the most likely value for the orbital inclination is 54 +/-1.5 deg. This inclination angle is consistent with those previously published, but has a much smaller error. This inclination implies a primary black hole mass of 6.95 +/-0.6 M_sun. While we do not see any evidence for contamination of our infrared light curves from other sources in the system, a conservative model with a contamination level of 15% increases the uncertainty in the inclination angle to 54 +4/-1.5 deg.

description: We discuss several aspects of particle production in: (a) time dependent electric field and (b) expanding Friedmann background. In the first part of the paper, we provide an algebraic mapping between the differential equations describing these two phenomena. This mapping allows a direct comparison between (a) and (b) and we highlight several interesting features of both cases using this approach. We determine the form of the (equivalent) electric field corresponding to different Friedmann spacetimes and discover, for example, a time-dependent electric field which, in a specific limit, leads to a Planck's spectrum of particles. We also discuss the conditions under which the particle production in an expanding background will be non-analytic in the parameter which encodes the coupling to the curved spacetime, in close analogy with the generalized Schwinger effect. In the second part of the paper, we study the situation in which both time dependent electric field and an expanding background are simultaneously present. We compute particle production rate in this context by several different methods paying special attention to its limiting forms and possible non-analytic behaviour. We also clarify several conceptual issues related to definitions of in-vacuum and out-vacuum in these systems.

description: Megalographa biloba (Stephens)
(Figure 6, 12, 17)
 Plusia biloba Stephens 1830: 104. Type: male, BMNH, London [examined]; Type locality: unknown. Note: The species was nominally described from England, where it occurs occasionally as a fall migrant from North America, but Stephens was also known to have mixed North American material in with European material in error.
 Diagnosis. Megalographa biloba was thoroughly characterized by Lafontaine and Poole (1991) with adults and genitalia figured. It differs from M. talamanca in several aspects. In the region where M. talamanca was collected, three M. biloba were taken at lower altitudes (2200–2600m). These M. biloba are smaller (male wing length: 14.1mm; female wing length: 15.6mm) and the silver hemispheres of the stigma are joined. The postmedian line is notched between M3 and CUA 1 in M. biloba; in M. talamanca there is a defined dash. The silver crescent below the reniform spot is entire and prominent in M. biloba but often broken and indistinct in M. talamanca. In the male genitalia the clavus is approximately the length of the clasper in M. biloba but 0.25X its length in M. talamanca (M. biloba clasper (0.31mm) and clavus (0.31mm); M. talamanca clasper (0.50mm) and clavus (0.13mm). The subbasal evagination in the vesica is larger in M. biloba. In the female genitalia, the ductus bursae is 0.25X as long as the corpus bursae, whereas in M. talamanca it is 0.13X as long, and the corpus bursae has a mesial twist where the bursa bends through a 90 o angle that is absent in M. talamanca.
 Distribution and Habitat. Megalographa biloba is widely distributed from southern United States southward through Central and South America to Argentina. It occurs farther north into northern United States and southern Canada as a seasonal migrant where it usually produces one or two generations each summer, but it rarely survives the winter in the northern part of its range. It also occurs in the Hawaiian Islands but it is unknown if the species occurs there naturally or was introduced. The species also occurs as a rare migrant in Great Britain, mainly in the summer and fall, but its travel to Europe could be aided by ships crossing the Atlantic.

description: Neutralization probabilities are presented for hyperthermal energy Na+ ions scattered from a Cu(001) crystal as a function of surface temperature and scattered velocity. A large enhancement in neutralization is observed as the temperature is increased. Velocity-dependent charge transfer regimes are probed by varying the incident energy, with the most prominent surface temperature effects occurring at the lowest energies. The data agree well with results obtained from a model based on the Newns-Anderson Hamiltonian, where the effects of both temperature and velocity are incorporated.

description: Observations have established that the diffuse intergalactic medium (IGM) at z ~ 3 is enriched to ~0.1-1% solar metallicity and that the hot gas in large clusters of galaxies (ICM) is enriched to 1/3-1/2 solar metallicity at z=0. Metals in the IGM may have been removed from galaxies (in which they presumably form) during dynamical encounters between galaxies, by ram-pressure stripping, by supernova-driven winds, or as radiation-pressure driven dust efflux. This study develops a method of investigating the chemical enrichment of the IGM and of galaxies, using already completed cosmological simulations. To these simulations, we add dust and (gaseous) metals, distributing the dust and metals in the gas according to three simple parameterized prescriptions, one for each enrichment mechanism. These prescriptions are formulated to capture the basic ejection physics, and calibrated when possible with empirical data. Our results indicate that dynamical removal of metals from >~ 3*10^8 solar mass galaxies cannot account for the observed metallicity of low-column density Ly-alpha absorbers, and that dynamical removal from >~ 3*10^10 solar mass galaxies cannot account for the ICM metallicities. Dynamical removal also fails to produce a strong enough mass-metallicity relation in galaxies. In contrast, either wind or radiation-pressure ejection of metals from relatively large galaxies can plausibly account for all three sets of observations (though it is unclear whether metals can be distributed uniformly enough in the low-density regions without overly disturbing the IGM, and whether clusters can be enriched quite as much as observed). We investigate in detail how our results change with variations in our assumed parameters, and how results for the different ejection processes compare. (Abridged)

description: Let $I \subseteq R = \mathbb{K}[x_1,\ldots,x_n]$ be a toric ideal, i.e., a binomial prime ideal. We investigate when the ideal $I$ can be "split" into the sum of two smaller toric ideals. For a general toric ideal $I$, we give a sufficient condition for this splitting in terms of the integer matrix that defines $I$. When $I = I_G$ is the toric ideal of a finite simple graph $G$, we give additional splittings of $I_G$ related to subgraphs of $G$. When there exists a splitting $I = I_1+I_2$ of the toric ideal, we show that in some cases we can describe the (multi-)graded Betti numbers of $I$ in terms of the (multi-)graded Betti numbers of $I_1$ and $I_2$.

 Habitat. Rocky/cobble intertidal, oyster bank, muddy substrate with shells.
 Remarks. Pilumnopeus convexus is one of the most common species found in a variety of habitats along the intertidal coast of the Persian Gulf. Apel (2001) stated that the records of P. vauquelini (Audouin, 1826) from the Persian Gulf by Stephensen (1946), Basson et al. (1977) and Hornby (1997) are more likely based upon misidentifications of P. convexus. Further taxonomic work is needed for being able to distinguish the different species of the genus, in particular these two closely related species.

description: The measurement of the stellar metallicity in galaxies is fundamental to understand their evolution across cosmic epochs, but is very difficult as it requires high signal-to-noise spectra. Benefiting from uniquely deep, UV rest-frame spectra of 600 star-forming galaxies at redshifts between 2 and 5.5 from the VANDELS survey, I derive the stellar metallicity from two absorption features at 1501 and 1719 Angstrom, which are metal sensitive features produced in the photosphere of young O-B stars. I will show for this sample the mass-metallicity relation, and a relation between the stellar metallicity and the UV-continuum slope (a proxy for the dust attenuation). The latter sheds light on the joint evolution of metal and dust content in galaxies between 2 and 3 Gyr after the Big Bang, and will allow the characterization of large statistical samples of galaxies at even earlier epochs with next generation telescopes.

 General distribution. Northwestern Indian Ocean: Red Sea, Persian Gulf, entered via the Suez Canal into the Mediterranean (Galil 2011).
 Habitat. Rocky/cobble with weeds and sandy/muddy intertidal to 11 m.
 Remarks. Apel (2001) examined material recorded as P. vauquelini by Stephensen (1946) and Basson et al. (1977) from the Persian Gulf and identified them as P. convexus. Apel (2001) believed that P. vauquelini does not occur in the Persian Gulf. He mentioned four morphologic characters allowing to distinguish these two closely related species (see Apel 2001: 99). Stephensen (1946) figured the male first gonopod, which is nearly similar to that of the present specimens of P. vauquelini. The present finding of the species confirms its occurrence in the Persian Gulf, although a thorough taxonomic work is necessary in order to establish the systematic position of these two species.

description: The transport of charged particles in disorganised magnetic fields is an important issue which concerns the propagation of cosmic rays of all energies in a variety of astrophysical environments, such as the interplanetary, interstellar and even extra-galactic media, as well as the efficiency of Fermi acceleration processes. We have performed detailed numerical experiments using Monte-Carlo simulations of particle propagation in stochastic magnetic fields in order to measure the parallel and transverse spatial diffusion coefficients and the pitch angle scattering time as a function of rigidity and strength of the turbulent magnetic component. We confirm the extrapolation to high turbulence levels of the scaling predicted by the quasi-linear approximation for the scattering frequency and parallel diffusion coefficient at low rigidity. We show that the widely used Bohm diffusion coefficient does not provide a satisfactory approximation to diffusion even in the extreme case where the mean field vanishes. We find that diffusion also takes place for particles with Larmor radii larger than the coherence length of the turbulence. We argue that transverse diffusion is much more effective than predicted by the quasi-linear approximation, and appears compatible with chaotic magnetic diffusion of the field lines. We provide numerical estimates of the Kolmogorov length and magnetic line diffusion coefficient as a function of the level of turbulence. Finally we comment on applications of our results to astrophysical turbulence and the acceleration of high energy cosmic rays in supernovae remnants, in super-bubbles, and in jets and hot spots of powerful radio-galaxies.

description: This paper examines results of a consumer survey measuring consumer awareness and attitudes concerning two labels, certified organic and certified Fair Trade. These labels provide information about the social, economic and environmental sustainability of the production and marketing practices of goods imported from the developing world. Conjoint analysis is used to measure how consumers value organic and fair trade compared to other attributes like price. Results indicate favorable attitudes and value placed on these the sustainable attributes, and imply a role for these labels to provide incentives for the adoption of more sustainable practices.

description: The interactions of methylphenanthrene (MP) isomers (1-MP, 3-MP, 4-MP, and 9-MP) with human serum albumin (HSA) were studied in simulated physiological conditions. A fluorescence analysis revealed that each MP formed a 1:1 ground-state complex with HSA. The binding constants at 308 K decreased in the order of 3-MP (9.13 × 104 L·mol−1) > 9-MP (3.57 × 104 L·mol−1) > 4-MP (2.37 × 104 L·mol−1) > 1-MP (1.46 × 104 L·mol−1), which was consistent with the docking results. The Kb values at 298 K, 308 K, and 318 K revealed that the β-isomer has a stronger binding affinity with HSA than the α-isomer. Thermodynamic and docking parameters showed that MPs combined with HSA through van der Waals forces. The results of the binding site competition experiment and molecular docking indicated that 4-MP bound at subdomain IIA in HSA molecule, while the other MPs bound at a site between subdomains IB and IIA. The circular dichroism (CD) spectra showed that the α-helical content of HSA reduced in the presence of 1-MP, 4-MP and 9-MP, while no significant change was observed in the presence of 3-MP. Further, the fluorescence spectroscopic studies revealed that the Vitamin B2 (VB2)-transporting function of HSA was inhibited by 3-MP and 9-MP, and enhanced by 1-MP and 4-MP. Moreover, the impact degrees of MPs on the VB2-transporting function had a positive correlation with the binding affinities of the MPs to HSA. HighlightsInteractions of MP isomers methylated at varying sites with HSA were studied.The α-substituted MP had a weaker affinity to HSA than β-substituted MP.Binding site of 4-MP in HSA was different from that of 1-MP/3-MP/9-MP.MP isomers unfolded the α-helical structure of HSA to varying degrees.Transporting function of HSA was inhibited by 3-MP/9-MP but enhanced by 1-MP/4-MP.

description: Two classes of gamma-ray bursts have been identified so far, characterized by durations shorter and longer than approximately 2 seconds. In 1998 two independent papers indicated the existence of the third class of the bursts roughly duration between 2 and 10 seconds. In this paper, using the full BATSE Catalog, the maximum likelihood estimation is presented, which gives a 0.5% probability to having only two subclasses. The Monte-Carlo simulation confirms this probability, too.

Dynamical scaling relations with radio and integral-field spectroscopy dat
Creators: name: Catinella, Barbara
Publisher: name: Zenodo
Year: 2021

description: Dynamical scaling relations such as the Tully-Fisher relation (TFR) link the baryonic and dark matter content of galaxies, and their slope and scatter encode important information on how galaxies assembled. Traditionally, most TFR work has been based on velocity widths obtained with 21 cm observations, but the advent of large integral-field spectroscopy (IFS) surveys has allowed us to revisit this important relation with new eyes. Interestingly, IFS studies seem to find more scatter at low stellar masses, compared to radio studies, which might be associated to the increasing importance of turbulent motions in these systems. The lack of overlapping samples with both IFS and 21 cm data has prevented a direct comparison until now. We present here the first results of SAMI-HI, a dedicated followup of galaxies with SAMI IFS data using the Arecibo radio telescope, and discuss the potential of the synergy between surveys of cold hydrogen gas and spatially-resolved optical spectroscopy.
