Radio Constraints on the Circumstellar Environment of the Type IIb Supernova SN 2024iss

Yuhei Iwata, Tomoki Matsuoka, Masanori Akimoto +6

Type~IIb supernovae exhibit diverse progenitor properties, and radio observations offer a unique probe of their mass-loss histories shortly before the explosion. We present Japanes…

AT2019ijn: a fast-rising, slow-decaying blue optical transient with exceptionally bright radio emission

Hucheng Ding, Xinwen Shu, Luming Sun +9

We report the discovery of a peculiar optical transient, AT2019ijn, occurred in the nuclear region of a dwarf galaxy at z=0.273. It rises rapidly to peak at a luminosity of Mg=-21.…

Broad-band Spectral Modeling of Large-Scale X-ray Jets in High-Redshift Quasars: An MHD-Informed Approach

Patryk Liniewicz, Łukasz Stawarz, Łukasz Stawarz +3

We present a systematic spectral analysis of kiloparsec-scale jets in high-redshift quasars, modeling their radio-to-X-ray emission as synchrotron radiation and inverse-comptonizat…

The nearby He-rich superluminous supernova SN 2021bnw during photospheric phases

A. Fiore, A. Kozyreva, L. Yan +40

Aim. We present and interpret the data of the nearby hydrogen-deficient but helium-rich superluminous supernova SN 2021bnw which reached a magnitude of -20.7 at maximum luminosity…

Las Cumbres Observatory Gravitational-Wave Follow-up in the Third and Fourth Observing Runs: Strengths and Weaknesses of a Rapid Response Galaxy Targeted Strategy

Ido Keinan, Iair Arcavi, D. Andrew Howell +34

We present a summary of gravitational-wave (GW) follow-up using the Las Cumbres Observatory global network of telescopes during the third (O3) and fourth (O4) observing runs of the…

Detection of a parsec-scale, compact, and fading ejecta from an accreting massive black hole

Chao Li, Ning Chang, Jun Yang +2

Dwarf galaxies, characterized by their low luminosities and masses, are excellent candidates for searches for intermediate-mass black holes (IMBHs), particularly when they show str…
