On the Clustering Bias of Unresolved Gamma-Ray Sources
Bhashin A. Thakore, Marco Regis, Michela Negro +4
The Unresolved -Ray Background (UGRB) encodes the collective emission of source populations that are too faint to be detected individually, and its cross-correlation with tracer…
Ad Astra White Paper: A Pitch for the Next 25 Years of NASA's Physics of the Cosmos Program
Eric Burns, Ivan Agullo, Igor Andreoni +7
Astrophysical observations of our universe have been key to our understanding of how the universe works. Shortly after the turn of the millennium, the National Research Council del…
A Search for GeV Emission from Magnetar Giant Flare Candidates with Fermi-LAT
Vikas Chand, Michela Negro, Nicola Omodei +5
The discovery of delayed GeV emission from the extragalactic magnetar giant flare (MGF) GRB 200415A, located in the nearby Sculptor galaxy, revealed for the first time that these r…
A new NASA Pioneer: the Globe Orbiting Soft X-ray Polarimeter (GOSoX)
Herman L Marshall, Sarah N T Heine, Alan Garner +16
The Globe Orbiting Soft X-ray Polarimeter (GOSoX) is a spectropolarimeter for the soft X-ray band. GOSoX is based on the Rocket Experiment Demonstration of a Soft X-ray Polarimeter…
Discriminating blazar emission models with high-energy polarimetry: Multi-band predictions and detectability
Sara Capecchiacci, Ioannis Liodakis, Haocheng Zhang +2
Polarimetric properties of blazars provide key constraints on the acceleration mechanisms powering their relativistic jets, the high-energy emission processes involved, and the com…
Detailed Timing, Spectral, and Polarimetric Analysis of Magnetar 1RXS J170849.0-400910
Rachael Stewart, George Younes, Alice Harding +5
We present a broadband timing, spectral, and polarimetric study of the magnetar 1RXS~J170849.0-400910 using XMM-Newton, NuSTAR, and IXPE. The pulse morphology evolves strongly acro…
Gamma-ray signature of superluminous supernovae: Fermi-LAT GeV detection of SN 2017egm and evidence of a central engine
F. Acero, A. Acharyya, A. Adelfio +116
Superluminous supernovae (SLSNe) are a rare class of transients with peak luminosities 10-100 times greater than those of standard core-collapse supernovae (SNe). The mechanisms po…
Magnetar Fireballs and Short Bursts: Curved Spacetime Lensing, QED Effects, Spectra, Polarization, and Impulse Responses
Zorawar Wadiasingh, Hoa Dinh Thi, Constantinos Kalapotharakos +12
Magnetar short bursts (SBs) are hard X-ray transients of durations s peaking at keV, and are prime targets for new high-energy missions and polarimeters. The…
Label Propagation for Identifying Gamma-Ray Burst Progenitors from Prompt Emission
Skye Strain, Nicoló Cibrario, Michela Negro +1
Gamma-ray bursts (GRBs) are the most energetic bursts of light in our universe, and rapid progenitor association of these events can lead to targeted and optimized follow-up observ…
Searching for dark matter X-ray lines from the Large Magellanic Cloud with eROSITA
Jorge Terol Calvo, Marco Taoso, Andrea Caputo +2
We perform a search for an X-ray monochromatic line arising from dark matter (DM) decay in the halo of the Large Magellanic Cloud. An emission line can be expected from two well-mo…
High-Energy Shock Breakout from Supernovae and Gamma-ray Bursts
Chris L. Fryer, Eric Burns, Joseph M. Colosimo +2
Cosmic explosions play a critical role in a broad range of astrophysical fields. Although considerable progress has been made to understand the explosive engines and their progenit…
Magnetic-field Order in the Southwestern Rim of RCW 86 Constrained Using X-Ray Polarimetry
Stefano Silvestri, Dmitry Prokhorov, Jacco Vink +97
RCW 86 is a supernova remnant whose origin has recently been linked to an off-center explosion within a cavity created by its progenitor star. In the southwestern region, the forwa…
Multi-Tracer Cross-Correlations of the Unresolved -Ray Sky
B. Thakore, M. Regis, M. Negro +4
Our understanding of the -ray sky has greatly advanced, yet studying the unresolved -ray background (UGRB) can unveil the nature of the faintest -ray source populations in…
