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…
Gamma-ray emission from particle illumination and shock-cloud interaction in the W51 Complex
Alan Sunny, Martina Cardillo
In the current era of very-high-energy (VHE) and ultra-high-energy (UHE) -ray astronomy, understanding Galactic PeVatrons and their acceleration mechanisms remains a primary obj…
The Origin of Multi-TeV Gamma-rays in LHAASO J0341+5258 via Cosmic Ray Illumination of Molecular Clouds
Abhijit Roy, Alan Sunny, Martina Cardillo +2
We investigate the origin of the ultra-high-energy -ray emission detected by the Large High Altitude Air Shower Observatory (LHAASO) from the source LHAASO J0341+5258, which has…
Chasing Gamma-Ray Signals from Binary Neutron Star Coalescences with the Cherenkov Telescope Array: Prospects and Observing Strategies
S. Abe, J. Abhir, A. Abhishek +457
The detection of gravitational waves (GWs) from a binary neutron star (BNS) merger by Advanced LIGO and Advanced Virgo (GW170817), together with its electromagnetic counterpart, th…
VHE gamma-ray intranight variability from BL Lacertae during the extreme flaring state of 2022
K. Abe, S. Abe, A. Abhishek +297
BL Lacertae (BL Lac), the archetypal blazar of its subclass and one of the most studied blazars in the last decades, has undergone a series of major multi-wavelength outbursts sinc…
Extreme Blazars Observed with MAGIC: Second Catalog Release
K. Abe, S. Abe, J. Abhir +353
Extremely high-peaked BL Lac objects - also named extreme blazars - are among the most energetic and persistent extragalactic accelerators in the Universe, defined by a synchrotron…
CTAO LST-1 observations of magnetar SGR 1935+2154: Deep limits on sub-second bursts and persistent tera-electronvolt emission
K. Abe, S. Abe, A. Abhishek +333
The Galactic magnetar SGR 1935+2154 has exhibited prolific high-energy (HE) bursting activity in recent years. Investigating its potential tera-electronvolt counterpart could provi…
VHE -ray observations of bright BL Lacs with the Large-Sized Telescope prototype (LST-1) of the CTAO
The CTAO-LST Project, :, K. Abe +331
Cherenkov Telescope Array Observatory (CTAO) is the next-generation ground-based gamma-ray observatory operating in the energy range from 20 GeV up to 300 TeV, with two sites in La…
Studying SNR-MC interactions as galactic PeVatrons in the era of CTAO and ASTRI Mini-Array
Alan Sunny, Martina Cardillo, Antonio Tutone
Supernova remnants (SNRs) are widely recognized as key accelerators of Galactic cosmic rays (CRs), supported by the detection of the characteristic pion bump in the gamma-ray spect…
GRB 221009A: Observations with LST-1 of CTAO and Implications for Structured Jets in Long Gamma-Ray Bursts
LST Collaboration, K. Abe, S. Abe +328
GRB 221009A is the brightest gamma-ray burst (GRB) observed to date. Extensive observations of its afterglow emission across the electromagnetic spectrum were performed, providing…
Detection of the Geminga pulsar at energies down to 20 GeV with the LST-1 of CTAO
The CTAO-LST Project, :, K. Abe +331
Geminga is the third gamma-ray pulsar firmly detected by imaging atmospheric Cherenkov telescopes (IACTs) after the Crab and the Vela pulsars. Most of its emission is expected at t…
Detection of RS Oph with LST-1 and modelling of its HE/VHE gamma-ray emission
CTA-LST Project, :, K. Abe +316
The recurrent nova RS Ophiuchi (RS Oph) underwent a thermonuclear eruption in August 2021. In this event, RS Oph was detected by the High Energy Stereoscopic System (H.E.S.S.), the…
Infinitely degenerate slowly rotating solutions in gravity
Alan Sunny, Semin Xavier, S. Shankaranarayanan
This work tests the no-hair conjecture in gravity models. No-hair conjecture asserts that all black holes in General Relativity coupled to any matter must be Kerr-Newman typ…
An exact model for evaporating primordial black holes in cosmological space-time
Semin Xavier, Alan Sunny, S. Shankaranarayanan
Primordial black holes (PBHs) in the mass range are considered as possible dark matter candidates as they are not subject to big-bang nucleosynthesis c…
