Constraints on the VHE counterpart of two binary black hole mergers observed by the MAGIC and CTAO LST-1 telescopes

K. Abe, S. Abe, J. Abhir +358

We present very-high-energy gamma-ray observations of two binary black hole merger candidates, GW240615_113620 and GW241125_010116, performed with the Major Atmospheric Gamma Imagi…

Constraining the synchrotron peak and estimating the VHE brightness of a sample of extreme high synchrotron peak blazars

Federica Sibani, Stefano Marchesi, Ettore Bronzini +5

We present the results of a multi-wavelength study of a population of X-ray bright (), non--ray detected high and extreme high synchrotron peak…

Is There New Physics Beyond 30 TeV in the BOAT?

Filip Rescic, Luis Recabarren Vergara, Michele Doro +1

We show that the GRB 221009A spectrum detected by LHAASO can be used to probe effects of quadratic subluminal Lorentz Invariance Violation (LIV) through the enhancement of the obse…

Recasting and Forecasting Dark Matter Limits Without Raw Data: A Generalized Algorithm for Gamma-Ray Telescopes

Giacomo D'Amico, Michele Doro, Michela De Caria

We present a novel method for both forecasting and recasting upper limits (ULs) on dark matter (DM) annihilation cross sections, , or decay lifetime $τ^{LL}…

Line emission search from DM annihilation in the Galactic Center with LST-1

Abhishek Abhishek, Shotaro Abe, Tomohiro Inada +4

Dark Matter remains a great mystery in modern physics. Among various candidates, the weakly interacting massive particles (WIMPs) scenario stands out and is under extensive study.…

Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory

K. Abe, S. Abe, J. Abhir +491

The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…
