SN 2021fxy: Mid-Ultraviolet Flux Suppression is a Common Feature of Type Ia Supernovae

J. M. DerKacy, S. Paugh, E. Baron +26

We present ultraviolet (UV) to near-infrared (NIR) observations and analysis of the nearby Type Ia supernova SN 2021fxy. Our observations include UV photometry from Swift/UVOT, UV…

Supermassive Black Hole Winds in X-rays: SUBWAYS. II. HST UV spectroscopy of winds at intermediate redshifts

M. Mehdipour, G. A. Kriss, M. Brusa +35

We present a UV spectroscopic study of ionized outflows in 21 active galactic nuclei (AGN), observed with the HST. The targets of the SUBWAYS sample were selected with the aim to p…

The disappearances of six supernova progenitors

Schuyler D. Van Dyk, Asia de Graw, Raphael Baer-Way +8

As part of a larger completed Hubble Space Telescope (HST) Snapshot program, we observed the sites of six nearby core-collapse supernovae (SNe) at high spatial resolution: SN 2012A…

Supernova 2020wnt: An Atypical Superluminous Supernova with a Hidden Central Engine

Samaporn Tinyanont, Stan E. Woosley, Kirsty Taggart +34

We present observations of a peculiar hydrogen- and helium-poor stripped-envelope (SE) supernova (SN) 2020wnt, primarily in the optical and near-infrared (near-IR). Its peak absolu…

A very luminous jet from the disruption of a star by a massive black hole

Igor Andreoni, Michael W. Coughlin, Daniel A. Perley +78

Tidal disruption events (TDEs) are bursts of electromagnetic energy released when supermassive black holes (SMBHs) at the centers of galaxies violently disrupt a star that passes t…
