2024GCN.38201....1I | We observed the field of GRB 241113A Siegel et al. GCN 38194 with the Sinistro instrument mounted on the 1m telescope of the LCO network located at Siding Spring Australia. Observations started on 2024 November 13 at 0955 UT 2.17 hr after the GRB trigger. We obtained a series of 3x180 s images in the SDSSr filter and of 5x120 s in the PS1z filter. Poor telescope tracking affects individual frames significantly disrupting the point spread function PSF in the stacked images. Nevertheless in the stacked zband image we detect a faint source consistent with the position of the optical source reported by SwiftUVOT Siegel et al. GCN 38194 and by other optical facilities Francile et al. GCN 38195 Huertas Ferrer et al. GCN 38197. We measure a preliminary magnitude of z 19.9 0.3 mag AB calibrated against nearby stars from the PanSTARRS catalog. We did not detect any source at the same position in the rband stacked image up to a limit of 20.1 mag. This project has received funding from the European Unions Horizon 2020 research and innovation program under grant agreement No 101004719. | 2024-11-01T00:00:00Z | ['2024GCN.38201....1I'] | null | GRB 241113A LCO optical observations | 2,024 | 0 | 0 | ['PUB_HTML'] | 0 | null |

2024Ap&SS.369....7S | The turbulent solar wind magnetic field shows structures that are characterized by sudden strong changes in the field magnitude andor direction. Such structures can be intermittent if their increments found from time series spacecraft measurements deviate from a Gaussian distribution. Current sheets are a possible source of such intermittency in plasma turbulence. We try three different techniques to find such events from the magnetometer data of the Magnetosphere Multiscale Mission MMS time derivative of the magnetic field partial variance increment PVI and a modified TsurutaniSmith TS method. We find a nonGaussian distribution of magnetic field time derivatives after noise reduction. These intermittent events are identified with varying levels of noise reduction to obtain an optimum value of filtering frequency. These events are found to match with those obtained by setting a suitable threshold value for the PVI which operates at larger time increments. The TS method which operates at even larger time increments also identifies some of these events. Identification of the same events in different MMS spacecraft confirms the presence of physical phenomena causing this intermittency. The magnetic field rotation angle across these events is also significantly larger than the average rotation angle for such intervals. Measurement of their duration indicates that these structures are of the order or even smaller than ion kinetic scales. Further high resolution observations and numerical simulations are required to probe their real spatialtemporal scales. | 2024-01-01T00:00:00Z | ['2024Ap&SS.369....7S', '10.1007/s10509-024-04266-x'] | ['Plasma turbulence', 'Current sheets', 'Solar wind', 'Intermittent structures', 'Sun: magnetic field'] | Identifying kinetic scale magnetic discontinuity structures in turbulent solar wind | 2,024 | 0 | 0.26 | ['PUB_HTML'] | 0 | null |
2024Ap&SS.369....6L | Astrophysical very high energy VHE gammarays with energies gt30 GeV are believed to result almost exclusively from the interactions of populations of highly relativistic particles with ambient matter or photon fields. The study of these VHE photons therefore allows us to examine the processes of particle acceleration in the Universe and the extreme environments in which they occur. Gammarays are also highly directional making them useful for studying the origin acceleration propagation and composition of cosmic rays. This study uses the Monte Carlo method to simulate the process of extensive air showers being initiated when primary incident inlineformula idIEq1mmlmathmmlmimmlmimmlmathinlineformularays with energies ranging from 10 GeV to 5 TeV interact with the atmosphere. The ultimate goal is to investigate and analyze the properties and lateral density distributions of Cherenkov light at different altitudes. The simulation considers various energies and zenith angles. The results show that a hump in the lateral density distribution of Cherenkov light is a distinctive feature of a inlineformula idIEq2mmlmathmmlmimmlmimmlmathinlineformulainitiated shower with the hump becoming less prominent at higher energy levels and altitudes. These significant findings not only facilitate better fitting of experimental data obtained from actual extensive air showers but also assist with estimating readings from detectors thus advancing our understanding of these processes. | 2024-01-01T00:00:00Z | ['2024Ap&SS.369....6L', '10.1007/s10509-024-04265-y'] | ['Gamma rays', 'Air shower', 'Monte Carlo methods', 'Lateral density distribution'] | Lateral density distributions of Cherenkov photons at different altitudes | 2,024 | 0 | 0.19 | ['PUB_HTML'] | 0 | null |
2024AntAs..18....2D | William Rowan Hamilton a mathematician who became Royal Astronomer of Ireland was a man of mixed reputation. This paper reassesses his life and work. We first look at his family his choice of women to whom he proposed marriage and his alleged alcoholism. After considering the institution of Dunsink Observatory where he was director and his post as Andrews Professor of Astronomy at Trinity College Dublin the paper focuses on why Hamilton applied for the position of Royal Astronomer of Ireland despite being not primarily an astronomer but a mathematician. Hamiltons astronomical work is compared to his output in related fields of science the output of contemporary astronomers and his later acceptance that he had lost interest in astronomy. Nonetheless top astronomers of the day looked up to him for his groundbreaking work in optics and fundamental mechanics for which he was aptly compared to Isaac Newton and JosephLouis Lagrange. His discovery of quaternions in 1843 which opened new vistas on algebra overshadowed many of his astronomical achievements. | 2024-06-01T00:00:00Z | ['2024AntAs..18....2D'] | null | Sir William Rowan Hamilton 180565 Royal Astronomer of Ireland | 2,024 | 0 | 0.27 | null | 0 | null |

2024DyAtO.10601448F | This study aims to investigate the role of tropicalextratropical interactions in the formation of atmospheric rivers as an important source of moisture in extremewidespread precipitation of Iran. Extreme precipitation events are extracted based on the 95th percentile index from 1989 to 2019 in Iran. Then the threshold of widespread precipitation is determined. A day is defined as having extremewidespread precipitation if onethird of the selected stations have mostly extreme precipitation. Finally 9 days with the highest extreme precipitation and spatial continuity are selected. The upper air data of the 9 selected days are extracted and accordingly synoptic charts are plotted. The used data include ERA5 which are extracted from the lower 800 and 850 hPa and middle 500 600 and 700 hPa levels. The results indicate an interaction with tropical circulation patterns by penetration of extratropical circulation patterns into tropical and subtropical regions. The interaction between patterns could lead to the formation of atmospheric rivers with tropical origin from ITCZ their transport to subtropical and extratropical regions and their moisture supply along the path by different moisture sources in tropical subtropical and extratropical regions. The formed atmospheric rivers are divided into two categories namely continental and oceanic based on their formation origin. The continental atmospheric river is formed at the lower level and in some cases at the middle level while the oceanic atmospheric river is only formed at the middle level. With the emergence of atmospheric rivers in Iran there have been extremewidespread precipitation events due to unstable conditions and rising atmosphere. | 2024-06-01T00:00:00Z | ['2024DyAtO.10601448F', '10.1016/j.dynatmoce.2024.101448'] | ['Circulation patterns', 'Interactions of circulation patterns', 'Atmospheric river', 'Extreme precipitation'] | Investigating role of tropicalextratropical interactions in formation of atmospheric rivers and supplying extremewidespread precipitation moisture in Iran A case study on March 25 2019 | 2,024 | 0 | 0.17 | ['PUB_HTML'] | 0 | null |
2015SPIE.9593E..16M | A networked gamma radiation detection system with directional sensitivity and energy spectral data acquisition capability is being developed by the National Security Technologies LLC Remote Sensing Laboratory to support the close and intense tactical engagement of law enforcement who carry out counterterrorism missions. In the proposed design three clusters of 2 4 16 sodium iodide crystals 4 each with digiBASEE for list mode data collection would be placed on the passenger side of a minivan. To enhance localization and facilitate rapid identification of isotopes advanced smart realtime localization and radioisotope identification algorithms like WAVRAD waveletassisted variance reduction for anomaly detection and NSCRAD nuisancerejection spectral comparison ratio anomaly detection will be incorporated. We will test a collection of algorithms and analysis that centers on the problem of radiation detection with a distributed sensor network. We will study the basic characteristics of a radiation sensor network and focus on the tradeoffs between false positive alarm rates true positive alarm rates and time to detect multiple radiation sources in a large area. Empirical and simulation analyses of critical system parameters such as number of sensors sensor placement and sensor response functions will be examined. This networked system will provide an integrated radiation detection architecture and framework with i a large nationally recognized search database equivalent that would help generate a common operational picture in a major radiological crisis ii a robust reach back connectivity for search data to be evaluated by home teams and finally iii a possibility of integrating search data from multiagency responders. | 2015-08-01T00:00:00Z | ['10.1117/12.2185843', '2015SPIE.9593E..16M'] | null | Networked gamma radiation detection system for tactical deployment | 2,015 | 0 | 0.14 | ['PUB_HTML'] | 0 | null |
2024DPS....5630707C | The Vera C. Rubin Observatory with its 8.4meter widefield telescope is expected to begin the Legacy Survey of Space and Time LSST within a year. One of the LSST objectives is to discover and catalog nearEarth objects NEOs including potential Earth impacting asteroids. We consider how reliably and frequently the LSST can be expected to detect and report nearterm potential impacts which we define to be impacts occurring within 60 days of first detection. There are two pathways for such reports singlenight trailed pairs of detections and multinight untrailed pairs. The former generally involves smaller closer objects while the latter tends to involve larger impactors farther out. We apply the Objects in Field OiF software suite Naidu et al. 2017 to the latest baseline LSST survey profile.

2024BSRSL..93..811D | The International Ultraviolet Explorer IUE satellite launched in 1978 by NASA and ESA has conducted highly successful longterm monitoring spectroscopic observations of many nearby lowredshift bright active galaxies including NGC 1068 NGC 5548 NGC 7469 Fairall 9MRK 335 and NGC 4151. Notably IUE has monitored NGC 4151 more intensively than any other active galaxy obtaining 414 spectra during its campaign from December 1 to 15 1993. Here we present results of our recent studies on the emission line and continuum variabilities characterised by the Rmax and Fvar parameters. From the analysis of the short timescale intense monitoring data we obtained Rmax values ranging between 2.140.02 and 1.620.01 corresponding to the UV continua 1270 and 2705 respectively. The corresponding Fvar values varied from 9.620.04 to 5.190.04 . Furthermore the Rmax values for the UV emission lines Ly C IV He II O III C III and Mg II have been found to be 4.090.06 4.550.05 13.650.68 4.780.17 2.760.02 respectively. The corresponding Fvar values obtained are 2.850.01 26.510.06 15.590.02 48.931.79 20.300.06 and 18.680.02 respectively. These results provide constraints on the amplitude of UV variability and the size of the broadline region BLR in low luminosity Seyfert galaxies. The decreasing Fvar amplitudes of the UV continuum with respect to increasing wavelengths are significant results of the present study. | 2024-06-01T00:00:00Z | ['2024BSRSL..93..811D', '10.25518/0037-9565.11887'] | ['NGC 4151', 'short-timescale variability', 'line and continuum fluxes', 'Rmax Parameter', 'Fvar amplitude'] | Nature of UV Variability in NGC 4151 from IUEs Intensive Monitoring Spectroscopic Data | 2,024 | 0 | 0.21 | ['PUB_HTML'] | 0 | null |

2024AdSpR..73.1549G | Remote sensing has already proven its capability in water quality studies. The technology enables the mapping of water quality parameters that affect its optical properties. Generally multispectral remote sensing data has been utilized for such analysis. Mostly the band rationing or simple regression approaches have been adapted to map the water quality however they result in qualitative estimates rather than quantitative. On the other hand sensor technology has made steep advancements from multispectral to hyperspectral. The hyperspectral data provides contiguous spectral information over several hundred narrow spectral bands. This emerging technique provides a more indepth means of investigating spatial spectral and temporal variations leading to more quantifiableaccurate estimates of the process under consideration. At present very few satellitebased hyperspectral data are available. Recently the Indian Space Research Organisation has initiated an airborne hyperspectral remote sensing campaign to cover the important earth features in India using Airborne VisibleInfrared Imaging Spectrometer Next Generation AVIRISNG sensor in collaboration with the National Aeronautics and Space Administration NASA. As the AVIRISNG hyperspectral data measures the spectral response in the wavelength range from 380 to 2510 nm at very narrow spectral bandwidth of 5 nm. These advanagtes of AVIRISNG datasets enable researchers to analyse the spectra of each and every pixel of the image spatially to match its spectral characteristics with the spectra collected in the field. In the present study this spectral similarity approach has been expoilted within the context of turbidity the optical property of water for Chilika Lake Odisha India using the AVIRISNG data and field reference spectra. The lake was surveyed synchronous to AVIRISNG flights over it during the month of December 2015. A fieldbased spectral library with respect to various concentrations of turbidity in the lake has been generated using sophisticated instruments like field spectroradiometer handheld Global Navigation Satellite System GNSS receiver and turbidimeter. The spectral angle mapper SAM spatialspectral contextual image analysis has been carried out to map the turbidity of the lake. It was observed that almost at each and every pixel the image spectra were matching with the fieldcollected spectra.

2024AdSpR..73.1379S | The present study highlights delineation of the distribution of understorey invasive plant species IPS in Mudumalai Tiger Reserve MTR Western Ghats India using very high resolution airborne imaging spectroscopy images by evaluating the performance of a Multiple Endmember Spectral Mixture Analysis MESMA. Lantana camara L. and Chromolaena odorata L. R.M.King amp H.Rob. have imposed a serious threat to natural ecosystems in MTR by altering the ecosystem processes. The Airborne VisibleInfrared Imaging SpectrometerNext Generation AVIRISNG based analysis delineated the distribution of understorey IPS viz. L. camara and C. odorata in MTR with an overall accuracy of 87 k 0.84 and 84 k 0.8 respectively with minimal rootmeansquare error RMSE of MESMA classification 0.001 to 0.0025. In MTR both the IPS were distributed in large parts and in association with all dominant canopy tree species barring Eucalyptus species. L. camara was majorly found in the southern parts of central MTR with high to very high presence covering 23.09 and 11.51 of the total area of central MTR respectively in association with Terminalia anogeissiana Gere amp Boatwr. and Tectona grandis L.f. Whereas C. odorata was dominantly found with high 18.11 area of central MTR to very high 11.85 area of central MTR intensity in the south and southeastern parts within the vicinity of T. anogeissiana and Terminalia elliptica Willd. The study highlights the utilization of high spectral agility in mapping of understorey IPS through spectral differentiation of the patchy distribution of IPS and its intermixing with other local species may be helpful in ecological restoration conservation of biodiversity and provisioning longterm management of ecosystem services in highly invaded tropical forests. | 2024-01-01T00:00:00Z | ['2024AdSpR..73.1379S', '10.1016/j.asr.2022.12.026'] | ['AVIRIS-NG', 'Hyperspectral', 'Invasive Plant Species', 'MESMA', 'Sentinel-1', 'Spectroradiometer'] | Mapping of understorey invasive plant species clusters of Lantana camara and Chromolaena odorata using airborne hyperspectral remote sensing | 2,024 | 0 | 0.38 | null | 0 | null |

2024AREPS..52..195K | Each of the halogens constrains a different aspect of volatile cycling in the solid Earth. F is moderately incompatible in the mantle and has a low mobility at Earths surface meaning that it is preferentially retained in the mantle and continental crust. In contrast Cl Br and I are strongly incompatible and highly soluble. Chloride is the dominant anion in seawater and many geofluids and a major component of evaporite minerals. Br and I are essential for life and significantly incorporated into organic matter that accumulates in marine sediments. Surficial fluids circulated into continental and oceanic crust incorporate surfacederived halogens into alteration minerals. As a result subducting slabs and arc lavas are weakly enriched in F and strongly enriched in Cl Br and I. Subduction has maintained mantle Cl and Br concentrations at relatively constant levels since Earths early differentiation but mantle ICl has decreased over time. | 2024-08-01T00:00:00Z | ['10.1146/annurev-earth-031621-111700', '2024AREPS..52..195K'] | null | Halogen Cycling in the Solid Earth | 2,024 | 0 | 0.16 | ['PUB_HTML', 'PUB_PDF'] | 1 | null |

2024E&PSL.62718513S | Glacier slip modulates sealevel rise. Most slip models assume quasiequilibrium process dynamics and debrisfree basal ice but observations regularly show debrisrich basal ice sliding under transient external forcings placing theory and observation in tension. Seismicity generated by slip icequake activity provides a window into subglacial dynamics but basal icequakes are often too sparse to resolve diagnostic trends at scales relevant to reveal slipfacilitating processes. We present a rich icequake catalog from an alpine glacier with subdiurnal and decametric resolution that overcomes these limitations. We find characteristic trends between subglacial hydrology slip and seismicity that corroborate emerging models of transient slip over hard beds and highlight the importance of basal debris in slip dynamics. Specifically icequakes are more abundant when subglacial cavities are likely largea configuration that favors reduced drag in debrisfree modelsbut this occurs as slip decelerates. Drag between entrained debris and the bed is enhanced under the same conditions and favors seismogenesis which reconciles this discrepancy and may indicate slipstabilizing feedback not considered in most models of glacier motion. Furthermore we characterize spatial temporal and magnitude scaling patterns in this seismic catalog consistent with trends observed in previous glacier seismicity studies suggesting that the slipfacilitating process dynamics characterized at Saskatchewan Glacier are relevant in other parts of the cryosphere. | 2024-02-01T00:00:00Z | ['10.1016/j.epsl.2023.118513', '2024E&PSL.62718513S'] | ['Glacier slip', 'Glacier seismicity', 'Transient slip', 'Subglacial processes'] | Icequake insights on transient glacier slip mechanics near channelized subglacial drainage | 2,024 | 0 | 0.25 | ['PUB_HTML'] | 3 | null |

2024DyAtO.10601453K | Current perspectives on lower frequency variations and secular warming have predominantly been shaped by traditional anomalies that assume an annual cycle AC with a timeinvariant amplitude. However this anomaly framework falls short in capturing the complexity of multiple periodic modes with intricate waveforms and time dependent amplitudethe traits in general shared by externally forced responses of complex dynamical systems. By allowing interannual amplitude modulation of ACs we show that the monotonic amplitude increases of the first AC of Sea Surface Temperature SST are manifested as the basinwide secular warming of the ocean surface. Notably the first SSTAC exhibits significant interannual variances and the largest linear warming rates in the Pacific Warm Pool. While the linear warming pattern mirrors that of a longterm mean SST it depicts an entirely different warming pattern on the surface of the tropical Pacific Ocean compared to those reported so far. Moreover all interannual warm El Nio and cold La Nia events in tropical Pacific regions are abnormal interannual modulations in the third and fourth ACs of SST respectively. Specifically a strong El Nio event occurs when a positive amplitude modulation leads to the overlap of two consecutive positive phases of the third AC of SST. Conversely the absence of such overlaps during negative amplitude modulations significantly contributes to the positive skewness of SST anomalies. No systematic decadal changes in the zonal propagation characteristics of SST in the eastern Pacific EP and central Pacific CP regions were detected. These findings underscore that the secular warming and lowfrequency events in EP and CP are intrinsic to three distinct ACs. | 2024-06-01T00:00:00Z | ['2024DyAtO.10601453K', '10.1016/j.dynatmoce.2024.101453'] | ['Sea surface warming pattern', 'Central pacific ENSO', 'Eastern pacific ENSO', 'Seasonal synchronization', 'Amplitude modulation'] | Decoding lowfrequency climate variations A case study on ENSO and ocean surface warming | 2,024 | 0 | 0.21 | ['PUB_HTML'] | 0 | null |
2016PhDT.......468S | Over the past decades star formation has been a very attractive field because knowledge of star formation leads to a better understanding of the formation of planets and thus of our solar system but also of the evolution of galaxies. Conditions leading to the formation of highmass stars are still under investigation but an evolutionary scenario has been proposed As a cold prestellar core collapses under gravitational force the medium warms up until it reaches a temperature of 100 K and enters the hot molecular core HMC phase. The forming central protostar accretes materials increasing its mass and luminosity and eventually it becomes sufficiently evolved to emit UV photons which irradiate the surrounding environment forming a hyper compact HC and then a ultracompact UC HII region. At this stage a very dense and very thin internal photondominated region PDR forms between the HII region and the molecular core. Information on the chemistry allows to trace the physical processes occurring in these different phases of star formation. Formation and destruction routes of molecules are influenced by the environment as reaction rates depend on the temperature and radiation field. Therefore chemistry also allows the determination of the evolutionary stage of astrophysical objects through the use of chemical models including the time evolution of the temperature and radiation field. Because HMCs host a very rich chemistry with high abundances of complex organic molecules COMs several astrochemical models have been developed to study the gas phase chemistry as well as grain chemistry in these regions. In addition to HMCs models models of PDRs have also been developed to study in particular photochemistry. So far few studies have investigated internal PDRs and only in the presence of outflows cavities. Thus these unique regions around HCUCHII regions remain to be examined thoroughly. My PhD thesis focuses on the spatiotemporal chemical evolution in HCUC HII regions with internal PDRs as well as in HMCs. The purpose of this study is first to understand the impact and effects of the radiation field usually very strong in these regions on the chemistry. Secondly the goal is to study the emission of various tracers of HCUCHII regions and compare it with HMCs models where the UV radiation field does not impact the region as it is immediately attenuated by the medium. Ultimately we want to determine the age of a given region using chemistry in combination with radiative transfer. | 2016-12-01T00:00:00Z | ['2016PhDT.......468S'] | null | Modeling chemistry in massive star forming regions with internal PDRs | 2,016 | 0 | 0.22 | ['AUTHOR_HTML'] | 0 | null |
2018cosp...42E1522H | The ionizing radiation environment in space pretenses substantial risks to human exploration. It consists primarily of 3 components Solar Particles Events SPE Galactic Cosmic Rays GCR and Van Allen Belts trapped protons that differ in elemental compositions energy spectra and intensities. The extravehicular environment is then modulated by interaction with the shielding provided by the spacecraft design and the body selfshielding provided differentially to internal organs and tissues. The Orion MultiPurpose Crew Vehicle MPCV is NASAs deep space exploration spacecraft developed for exploration of the solar system. Orion is designed by an industry team lead by Lockheed Martin as the prime contractor. Spacecraft shielding is quantified analytically using Computer Aided Design CAD tools to great details. However NASA is using the Computerized Anatomical Male CAM model to quantify the body selfshielding to internal organs and tissues which is dated back to the 70s and cannot be verified by the modern CAD tools. For this reason a highly detailed radiationspecific model representing the most anatomically correct geometric of the human body has been developed by Lockheed Martin Space to be used in analyzing radiation dose distribution for human. The model was derived from the BodyParts3D database. BodyParts3D is a threedimensional anatomical structure database for body segments representing the wholebody model for an adult human. The model contains 2234 unique geometric surfaces with no solid regions. A program was developed to convert surface models to solid representation with no loss in geometric quality. The models were then divided into 25 assemblies by organ levels and organ points were uniformly distributed inside each organ. Multiple analyses were performed with the model. Analyses included tracing rays in CAD through the body geometry converting results from raytracing information to areal density distributions and creating crosssectional views. This presentation will discuss the radiation exposure to trapped protons solar particle events SPE and galactic cosmic rays GCR at each organ dose point in the body by combining space radiation transport models with the detailed bodyshielding mass of BodyParts3D and CAM respectively and calculating the dose equivalent to organs and the effective dose per NCRP132 weighting factors.The model was derived from the BodyParts3D database.BodyParts3D The Database Center for Life Science licensed under CC AttributionShare Alike 2.1 Japan. | 2018-07-01T00:00:00Z | ['2018cosp...42E1522H'] | null | New Human Anatomical Model For Crew Radiation Analysis | 2,018 | 0 | 0.18 | null | 0 | null |
2017Ap&SS.362...34L | Rotational state of space debris will be influenced by eddy current torque which is produced by the conducting body rotating within the geomagnetic field. Former expressions of instantaneous torque established in bodyfixed coordinate system will change in space during rotation due to the variation of the coordinate system. In order to further investigate the evolution of the rotation of space debris subjected to the eddy current torque approximate expressions of mean eddy current torque in inertial coordinate system are obtained from the average of the Euler dynamics equations under the assumption that two of the principal moments of inertia of the space debris are similar. Then the expressions are verified through numerical simulation in which the orientation of the averaged variation of angular momentum is in agreement with the torque from the expressions which is on an identical plane with magnetic field and the angular momentum. The torque and the averaged variation of the angular momentum have the same evolution trend during rotation in spite of minor deviations of their values. | 2017-02-01T00:00:00Z | ['10.1007/s10509-017-3012-4', '2017Ap&SS.362...34L'] | ['Eddy current torque', 'Euler kinematical equations', 'Space debris'] | Approximate expressions of mean eddy current torque acted on space debris | 2,017 | 0 | 0.12 | ['PUB_HTML'] | 1 | null |
