Probing jet base emission of M87* with the 2021 Event Horizon Telescope observations
Saurabh, Hendrik Müller, Sebastiano D. von Fellenberg +282
We investigate the presence and spatial characteristics of the jet base emission in M87* at 230 GHz, enabled by the enhanced uv coverage in the 2021 Event Horizon Telescope (EHT) o…
The broad-lined type Ic supernova 2020lao experienced an energetic explosion with no central-engine signatures
M. D. Stritzinger, T. J. Moriya, S. Bose +18
We present infant-phase observations of the SN Ic-BL 2020lao, including optical spectroscopy beginning 48 hrs after explosion. The explosion time was constrained by power-law fits…
Cosmological Evolution of Gamma Ray Bursts
Sujay Champati, Vahé Petrosian, Maria G. Dainotti
Gamma-ray bursts (GRBs) are classified as long (LGRBs) and short (SGRBs), with collapsars and compact-object mergers (NS-NS or NS-Black Holes) as progenitors, respectively. LGRBs a…
Probing evolution of Long GRB properties through their cosmic formation history aided by Machine Learning predicted redshifts
Dhruv S. Bal, Aditya Narendra, Maria Giovanna Dainotti +3
Gamma-ray Bursts (GRBs) are valuable probes of cosmic star formation reaching back into the epoch of reionization, and a large dataset with known redshifts () is an important in…
Horizon-scale variability of M87* from 2017--2021 EHT observations
The Event Horizon Telescope Collaboration
We report three epochs of polarized images of M87* at 230\,GHz using data from the Event Horizon Telescope (EHT) taken in 2017, 2018, and 2021. The baseline coverage of the 2021 ob…
Far-infrared probing with PRIMA into particle acceleration associated with relativistic jets from active galactic nuclei
Naoki Isobe, Takao Nakagawa, Motoki Kino +3
It is presented that the Probe far-Infrared Mission for Astrophysics (PRIMA) has a high potential to study particle acceleration phenomena associated with jets emanating from activ…
