Revisiting GW170817 at milliarcsecond scale: high-precision constraints on jet geometry and
Kelly Gourdji, Adam T. Deller, Chris Flynn +4
The historic detection of gravitational waves from the electromagnetically bright binary neutron star merger GW170817 enabled the first standard siren measurement of Hubble's const…
AT2024wpp: An Extremely Luminous Fast Ultraviolet Transient Powered by Accretion onto a Black Hole
Daniel A. Perley, Anna Y. Q. Ho, Zoë McGrath +69
We present the discovery of AT 2024wpp ("Whippet"), a fast and luminous 18cow-like transient. At a redshift of z=0.0868, revealed by Keck Cosmic Web Imager spectroscopy of its fain…
X-ray Transmission Through Photoionized Gas with Moderate Thomson Optical Depth
Taya Govreen-Segal, Ehud Nakar, Eliot Quataert
We model the absorption of X-rays by gas obscuring the source and photoionized by it. We consider a broad range of column densities, including both Thomson-thin and Thomson-thick m…
AT2018cow Powered by a Shock in Aspherical Circumstellar Media
Taya Govreen-Segal, Ehud Nakar, Kenta Hotokezaka +2
We present a quantitative model for the luminous fast blue optical transient AT2018cow in which a shock propagating through an aspherical circumstellar medium (CSM) produces the X-…
