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…
Transverse Oscillations and Wave Propagation in the Magnetically Dominated M87 Jet
Hyunwook Ro, Motoki Kino, Kazuhiro Hada +6
We present an in-depth analysis of transverse oscillations in the M87 jet, as identified in our previous study (Ro et al. 2023a), which reported oscillatory patterns with a charact…
Locating the missing large-scale emission in the jet of M87* with short EHT baselines
Boris Georgiev, Paul Tiede, Sebastiano D. von Fellenberg +280
In Very-Long Baseline Interferometric arrays, nearly co-located stations probe the largest scales and typically cannot resolve the observed source. In the absence of large-scale st…
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…
Magnetohydrodynamic Simulations of Transonic Accretion Flows
Raj Kishor Joshi, Antonios Tsokaros, Sanjit Debnath +2
Theoretical studies of transonic accretion onto black holes reveal a wide range of possible solutions, broadly classified into smooth flows and flows featuring shocks. Accretion so…
