Thermal Electrons in Mildly-relativistic Synchrotron Blast-waves
Ben Margalit, Eliot Quataert
Numerical models of collisionless shocks robustly predict an electron distribution comprised of both thermal and non-thermal electrons. Here, we explore in detail the effect of the…
A Toy Model for the Time-Frequency Structure of Fast Radio Bursts: Implications for the CHIME Burst Dichotomy
Brian D. Metzger, Navin Sridhar, Ben Margalit +2
We introduce a toy model for the time-frequency structure of fast radio bursts (FRB), in which the observed emission is produced as a narrowly-peaked intrinsic spectral energy dist…
Luminous Millimeter, Radio, and X-ray Emission from ZTF20acigmel (AT2020xnd)
Anna Y. Q. Ho, Ben Margalit, Michael Bremer +7
Observations of the extragalactic () transient AT2018cow established a new class of energetic explosions shocking a dense medium, which produce luminous emission at milli…
Optical to X-ray Signatures of Dense Circumstellar Interaction in Core-Collapse Supernovae
Ben Margalit, Eliot Quataert, Anna Y. Q. Ho
Progenitors of core-collapse supernovae (SNe) can shed significant mass to circumstellar material (CSM) in the months--years preceding core-collapse. The ensuing SN explosion launc…
Late-Time Evolution and Modeling of the Off-Axis Gamma-ray Burst Candidate FIRST J141918.9+394036
K. P. Mooley, B. Margalit, C. J. Law +12
We present new radio and optical data, including very long baseline interferometry, as well as archival data analysis, for the luminous decades-long radio transient FIRST J141918.9…
Analytic Light Curves of Dense CSM Shock Breakout and Cooling
Ben Margalit
Dense circumstellar material (CSM) is thought to play an important role in observed luminous optical transients: if such CSM is shocked, e.g. by ejecta expelled from the progenitor…
