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…

Optical Microlensing by Primordial Black Holes with IACTs

Konstantin Pfrang, Tarek Hassan, Elisa Pueschel

Primordial black holes (PBHs), hypothesized to be the result of density fluctuations during the early universe, are candidates for dark matter. When microlensing background stars,…

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…

Understanding the extreme luminosity of DES14X2fna

M. Grayling, C. P. Gutiérrez, M. Sullivan +66

We present DES14X2fna, a high-luminosity, fast-declining type IIb supernova (SN IIb) at redshift , detected by the Dark Energy Survey (DES). DES14X2fna is an unusual memb…
