Synchrotron Emission from Cooled Particle Distributions
Ross Ferguson, Ben Margalit
The paper derives analytic fitting functions for synchrotron emission and absorption from cooled electron distributions, covering both power‑law and thermal cases, to improve model…
Multiwavelength Analysis of Six Luminous Fast Blue Optical Transients
Cassie Sevilla, Anna Y. Q. Ho, Nayana A. J. +43
We present multiwavelength observations and analysis of six luminous fast blue optical transients (LFBOTs) discovered in Zwicky Transient Facility (ZTF) survey data. We identified…
Old and Bright: The Remarkable Radio Brightening of the Engine-driven SN 2012au Several Years After Explosion Signals the Birth of a PWN
Eli Wiston, Raffaella Margutti, A. J. Nayana +23
We present the results from an extensive broad-band (radio to X-rays) observing campaign of the engine-driven Type Ib SN 2012au in the first 13 years of evolution. The early-time (…
No Sign of a Magnetar Remnant Following the Kilonova-Producing Long GRB 211211A Years Later
Genevieve Schroeder, Ben Margalit, Brian D. Metzger +9
In addition to a -ray burst (GRB), the merger of two neutron stars may produce a temporarily or indefinitely stable neutron star remnant with a strong magnetic field (a "magnet…
Characterizing Supernova Host Galaxies with FrankenBlast: A Scalable Tool for Transient Host Galaxy Association, Photometry, and Stellar Population Modeling
Anya E. Nugent, V. Ashley Villar, Alex Gagliano +5
We present FrankenBlast, a customized and improved version of the Blast web application. FrankenBlast associates transients to their host galaxies, performs host photometry, and ru…
The Host Galaxies of Fast Radio Bursts Track a Combination of Stellar Mass and Star Formation, Similar to Type Ia Supernovae
Asaf Horowicz, Ben Margalit
We develop a new statistical framework for studying the host galaxies of astrophysical sources that accounts for both redshift evolution and the multi-variate nature of host-galaxy…
