AT 2020afjz (TSS2020a): The First Fast Extragalactic Transient Discovered by TESS
Ryan Ridden-Harper, Hugh Roxburgh, Clarinda Montilla +13
We report the discovery of AT 2020afjz (TSS2020a): the first hour-scale extragalactic transient discovered in optical wavelengths whose complete evolution -- from explosion onset t…
Two new highly scattered fast radio bursts: evidence for scatter broadening by the circumsource medium
Joscha N. Jahns-Schindler, Keith W. Bannister, Adam T. Deller +17
We found two highly scattered Fast Radio Bursts (FRBs) during commissioning of the Commensal Realtime ASKAP Fast Transient COherent (CRACO) backend. FRB 240210D and FRB 240312D hav…
Detecting HI Absorption in FRB Spectra: Modern Prospects and Scientific Utility
Hugh Roxburgh, Marcin Glowacki, Apurba Bera +1
Fast radio bursts (FRBs) emit broadband radio emission that may, in rare cases, encode atomic hydrogen (HI) absorption signals as they traverse the interstellar medium of their hos…
SN 2019vxm: A Shocking Coincidence between Fermi and TESS
Zachary G. Lane, Ryan Ridden-Harper, Sofia Rest +37
Shock breakout and, in some cases, jet-driven high-energy emission are increasingly recognized as key signatures of the earliest phases of core-collapse supernovae, especially in T…
A Comprehensive Investigation of Gamma-Ray Burst Afterglows Detected by TESS
Hugh Roxburgh, Ryan Ridden-Harper, Zachary G. Lane +9
Gamma-ray bursts produce afterglows that can be observed across the electromagnetic spectrum and can provide insight into the nature of their progenitors. While most telescopes tha…
