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 Faintest, Extremely Variable X-ray Tidal Disruption Event from a Supermassive Black Hole Binary?
Mengqiu Huang, Yongquan Xue, Shuo Li +30
Tidal disruption events (TDEs), which occur when stars enter the tidal radii of supermassive black holes (SMBHs) and are subsequently torn apart by their tidal forces, represent in…
Pulse profile modelling of the accretion-powered millisecond pulsar SAX J1808.4-3658 using NICER data from its 2019 and 2022 outbursts
Bas Dorsman, Tuomo Salmi, Anna L. Watts +5
Pulse profile modelling is a relativistic ray-tracing technique that has provided constraints on parameters, with a focus on mass and radius, of five rotation-powered millisecond p…
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…
The 2025 outburst of IGR J17511-3057: timing and spectral insights from NICER and NuSTAR
A. Sanna, G. K. Jaisawal, T. E. Strohmayer +13
IGR J17511-3057 was observed in a new outburst phase starting in February 2025 and lasting at least nine days. We investigated the spectral and temporal properties of IGR J17511-30…
A HyperFlash and ÉCLAT view of the local environment and energetics of the repeating FRB 20240619D
O. S. Ould-Boukattine, A. J. Cooper, J. W. T. Hessels +16
Time-variable propagation effects provide a window into the local plasma environments of repeating fast radio burst (FRB) sources. Here we report high-cadence observations of FRB 2…
Constraining gamma-ray burst parameters with the first ultra-high energy neutrino event KM3-230213A
KM3NeT Collaboration, O. Adriani, A. Albert +278
Context: The detection of the highest energy neutrino observed to date by KM3NeT, with an estimated energy of 220 PeV, opens up new possibilities for the study and identification o…
Probing Evolution of Long Gamma-Ray Burst Properties through Their Cosmic Formation History
Nikita S. Khatiya, Maria Giovanna Dainotti, Aditya Narendra +3
The astrophysics of Long GRB (LGRB) progenitors as well as possible cosmological evolution in their properties still poses many open questions. Previous studies suggest that the LG…
