SN 2021adxl: A luminous nearby interacting supernova in an extremely low metallicity environment

S. J. Brennan, S. Schulze, R. Lunnan +17

SN 2021adxl is a slowly evolving, luminous, Type IIn supernova with asymmetric emission line profiles, similar to the well-studied SN 2010jl. We present extensive optical, near-ult…

Minutes-duration Optical Flares with Supernova Luminosities

Anna Y. Q. Ho, Daniel A. Perley, Ping Chen +74

In recent years, certain luminous extragalactic optical transients have been observed to last only a few days. Their short observed duration implies a different powering mechanism…

Multi-year characterisation of the broad-band emission from the intermittent extreme BL Lac 1ES~2344+514

H. Abe, S. Abe, V. A. Acciari +232

The BL Lac 1ES 2344+514 is known for temporary extreme properties (e.g., a shift of the synchrotron SED peak energy above 1keV). While those extreme states were so fa…

Observational properties of a bright type Iax SN 2018cni and a faint type Iax SN 2020kyg

Mridweeka Singh, Devendra. K. Sahu, Raya Dastidar +29

We present the optical photometric and spectroscopic analysis of two type Iax SNe 2018cni and 2020kyg. SN 2018cni is a bright type Iax SN (M = 17.810.21 mag) whe…

Updated Orbital Ephemeris and Detection of Superhump Modulation in X-ray Band for the Ultra-Compact Low Mass X-ray Binary 4U 1820-30

Yi Chou, Yao-Wun Jhang

The 4U 1820-30 is a ultra-compact low mass X-ray binary (LMXB) near the center of the globular cluster NGC 6624. Its negative orbital period derivative, observed from the phase evo…

Deciphering the unusual stellar progenitor of GRB 210704A

R. L. Becerra, E. Troja, A. M. Watson +16

GRB~210704A is a burst of intermediate duration (~s) followed by a fading afterglow and an optical excess that peaked about 7 days after the explosion. Its propert…

The optical behaviour of BL Lacertae at its maximum brightness levels: a blend of geometry and energetics

C. M. Raiteri, M. Villata, S. G. Jorstad +13

In 2021 BL Lacertae underwent an extraordinary activity phase, which was intensively followed by the Whole Earth Blazar Telescope (WEBT) Collaboration. We present the WEBT optical…

Over 500 Days in the Life of the Photosphere of the Type Iax Supernova SN 2014dt

Yssavo Camacho-Neves, Saurabh W. Jha, Barnabas Barna +20

Type Iax supernovae (SN Iax) are the largest known class of peculiar white dwarf supernovae, distinct from normal Type Ia supernovae (SN Ia). The unique properties of SN Iax, espec…

The optical light curve of GRB 221009A: the afterglow and the emerging supernova

M. D. Fulton, S. J. Smartt, L. Rhodes +46

We present extensive optical photometry of the afterglow of GRB~221009A. Our data cover \,days from the time of \textit{Swift} and \textit{Fermi} GRB detections. Photom…
