Detection of Partial Coherence due to Multipath Propagation for FRB 20220413B with CHIME/FRB

Zarif Kader, Evan Davies-Velie, Matt Dobbs +7

Fast radio bursts (FRBs) are a millisecond-long transient phenomenon that propagate across extragalactic distances and are effectively a point source. Radio wave propagation…

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…

Normal or transitional? The evolution and properties of two type Ia supernovae in the Virgo cluster

L. Izzo, C. Gall, N. Khetan +47

Type Ia supernovae (SNe Ia) are among the most precise cosmological distance indicators used to study the expansion history of the Universe. The vast increase of SN Ia data due to…

Radio properties of the quasi-periodic eruption source RXJ1301.9+2747 at parsec scales

S. D. von Fellenberg, R. Arcodia, P. Benke +6

Quasi-periodic eruptions (QPEs) are repeating soft X-ray flares associated with galactic nuclei. Several recent works have found evidence that the accretion flow in the galactic nu…

Searching for Exotrojans in Pulsar Systems

Jackson D. Taylor, Emmanuel Fonseca, Lankeswar Dey +50

Trojan asteroids are found in the equilateral triangle Lagrange points of the Sun-Jupiter system in great number, though they also exist less prolifically in other parts of the Sol…

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…
