Combined searches for dark matter in dwarf spheroidal galaxies observed with the MAGIC telescopes, including new data from Coma Berenices and Draco

MAGIC Collaboration, V. A. Acciari, S. Ansoldi +191

Milky Way dwarf spheroidal galaxies (dSphs) are among the best candidates to search for signals of dark matter annihilation with Imaging Atmospheric Cherenkov Telescopes, given the…

Multiwavelength study of the gravitationally lensed blazar QSO B0218+357 between 2016 and 2020

MAGIC Collaboration, V. A. Acciari, S. Ansoldi +208

We report multiwavelength observations of the gravitationally lensed blazar QSO B0218+357 in 2016-2020. Optical, X-ray and GeV flares were detected. The contemporaneous MAGIC obser…

Search for Very High-Energy Emission from the millisecond pulsar PSR J0218+4232

V. A. Acciari, S. Ansoldi, L. A. Antonelli +198

PSR J0218+4232 is one of the most energetic millisecond pulsars known and has long been considered as one of the best candidates for very high-energy (VHE; >100 GeV) gamma-ray emis…

First detection of VHE gamma-ray emission from TXS~1515--273, study of its X-ray variability and spectral energy distribution

MAGIC Collaboration, V. A. Acciari, S. Ansoldi +196

We report here on the first multi-wavelength (MWL) campaign on the blazar TXS 1515-273, undertaken in 2019 and extending from radio to very-high-energy gamma rays (VHE). Up until n…

Investigation of the correlation patterns and the Compton dominance variability of Mrk 421 in 2017

MAGIC Collaboration, V. A. Acciari, S. Ansoldi +284

We present a detailed characterisation and theoretical interpretation of the broadband emission of the paradigmatic TeV blazar Mrk 421, with special focus on the multi-band flux co…

Catalog of Long-Term Transient Sources in the First 10 Years of Fermi-LAT Data

L. Baldini, J. Ballet, D. Bastieri +112

We present the first Fermi Large Area Telescope (LAT) catalog of long-term -ray transient sources (1FLT). This comprises sources that were detected on monthly time intervals dur…

Gamma rays from Fast Black-Hole Winds

LAT Collaboration

Massive black holes at the centers of galaxies can launch powerful wide-angle winds that, if sustained over time, can unbind the gas from the stellar bulges of galaxies. These wind…

Electron-beam interaction with emission-line clouds in blazars

Christoph Wendel, Josefa Becerra González, David Paneque +1

Context: An electron-positron beam escaping from the magnetospheric vacuum gap of an accreting black hole interacts with recombination-line photons from surrounding gas clouds. Inv…
