Constraining the TeV gamma-ray emission of SN 2024bch, a possible type IIn-L from a red supergiant progenitor. Multiwavelength observations and analysis of the progenitor

The CTAO-LST Project, :, K. Abe +332

We present very high-energy optical photometry and spectroscopic observations of SN 2024bch in the nearby galaxy NGC 3206 (\sim 20 Mpc). We used gamma-ray observations performed wi…

Joint searches by FACT, H.E.S.S., MAGIC and VERITAS for VHE gamma-ray emission associated with neutrinos detected by IceCube

Fabian Schüssler, Halim Ashkar, Elisa Bernardini +11

The sources of the astrophysical flux of high-energy neutrinos detected by IceCube are still largely unknown, but searches for temporal and spatial correlation between neutrinos an…

Dark Matter searches in Dwarf Galaxies with the Southern Wide-field Gamma-ray Observatory

Micael Andrade, Aion Viana

Dark matter is thought to make up most of the matter density of the Universe, yet its true nature remains uncertain. Among dark matter theories, Weakly Interacting Massive Particle…

Multi-messenger characterization of Mrk 501 during historically low X-ray and -ray activity

MAGIC collaboration, H. Abe, S. Abe +322

We study the broadband emission of Mrk 501 using multi-wavelength observations from 2017 to 2020 performed with a multitude of instruments, involving, among others, MAGIC, Fermi-LA…

Observation of burst activity from SGR1935+2154 associated to first galactic FRB with H.E.S.S

D. Kostunin, H. Ashkar, F. Schüssler +1

Fast radio bursts (FRB) are enigmatic powerful single radio pulses with durations of several milliseconds and high brightness temperatures suggesting coherent emission mechanism. F…

Broadband Multi-wavelength Properties of M87 during the 2017 Event Horizon Telescope Campaign

J. C. Algaba, J. Anczarski, K. Asada +36

In 2017, the Event Horizon Telescope (EHT) Collaboration succeeded in capturing the first direct image of the center of the M87 galaxy. The asymmetric ring morphology and size are…
