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…

X-ray Polarization Observations of BL Lacertae

Riccardo Middei, Ioannis Liodakis, Matteo Perri +143

Blazars are a class of jet-dominated active galactic nuclei with a typical double-humped spectral energy distribution. It is of common consensus the Synchrotron emission to be resp…

SN 2022ann: A type Icn supernova from a dwarf galaxy that reveals helium in its circumstellar environment

K. W. Davis, K. Taggart, S. Tinyanont +64

We present optical and near-infrared (NIR) observations of the Type Icn supernova (SN Icn) 2022ann, the fifth member of its newly identified class of SNe. Its early optical spectra…

Near-Infrared and Optical Observations of Type Ic SN 2021krf: Luminous Late-time Emission and Dust Formation

Aravind P. Ravi, Jeonghee Rho, Sangwook Park +29

We present near-infrared (NIR) and optical observations of the Type Ic supernova (SN Ic) SN 2021krf obtained between days 13 and 259 at several ground-based telescopes. The NIR spe…

A fast rising tidal disruption event from a candidate intermediate mass black hole

C. R. Angus, V. F. Baldassare, B. Mockler +36

Massive black holes (BHs) at the centres of massive galaxies are ubiquitous. The population of BHs within dwarf galaxies, on the other hand, is evasive. Dwarf galaxies are thought…

Polarized Blazar X-rays imply particle acceleration in shocks

Ioannis Liodakis, Alan P. Marscher, Iván Agudo +125

Most of the light from blazars, active galactic nuclei with jets of magnetized plasma that point nearly along the line of sight, is produced by high-energy particles, up to $\sim 1…

The Circumstellar Environments of Double-Peaked, Calcium-strong Supernovae 2021gno and 2021inl

Wynn Jacobson-Galán, Padma Venkatraman, Raffaella Margutti +42

We present panchromatic observations and modeling of calcium-strong supernovae (SNe) 2021gno in the star-forming host galaxy NGC 4165 (D = 30.5 Mpc) and 2021inl in the outskirts of…
