Performance update of an event-type based analysis for the Cherenkov Telescope Array
(2023)PoS: Proceedings of Science ~ 38th International Cosmic Ray ConferenceThe Cherenkov Telescope Array (CTA) will be the next-generation observatory in the field of very-high-energy (20 GeV to 300 TeV) gamma-ray astroparticle physics. The traditional approach to data analysis in this field is to apply quality cuts, optimized using Monte Carlo simulations, on the data acquired to maximize sensitivity. Subsequent steps of the analysis typically use the surviving events to calculate one set of instrument response ...Conference Paper -
Progress in Diamond Detector Development
(2023)PoS: Proceedings of Science ~ 10th International Workshop on Semiconductor Pixel Detectors for Particles and ImagingDetectors based on Chemical Vapor Deposition (CVD) diamond have been used successfully in Luminosity and Beam Condition Monitors (BCM) in the highest radiation areas of the LHC. Future experiments at CERN will accumulate an order of magnitude larger fluence. As a result, an enormous effort is underway to identify detector materials that can operate under fluences of 1 · 1016 n cm−2 and 1 · 1017 n cm−2. Diamond is one candidate due to its ...Conference Paper -
Joint Observation of the Galactic Center with MAGIC and CTA-LST-1
(2023)PoS: Proceedings of Science ~ Proceedings of 38th International Cosmic Ray Conference — PoS(ICRC2023)MAGIC is a system of two Imaging Atmospheric Cherenkov Telescopes (IACTs), designed to detect very-high-energy gamma rays, and is operating in stereoscopic mode since 2009 at the Observatorio del Roque de Los Muchachos in La Palma, Spain. In 2018, the prototype IACT of the Large-Sized Telescope (LST-1) for the Cherenkov Telescope Array, a next-generation ground-based gamma-ray observatory, was inaugurated at the same site, at a distance ...Conference Paper -
Evidence of hadronic origin of the gamma-ray emission from the nova RS Oph by the MAGIC telescopes
(2023)PoS: Proceedings of Science ~ Proceedings of 38th International Cosmic Ray Conference — PoS(ICRC2023)RS Ophiuchi (RS Oph) is a symbiotic recurrent nova that shows eruptive events roughly every 15 years. On August 8th, 2021, RS Oph erupted with its latest outburst. This event was detected by a wide range of multi-wavelength (MWL) instruments from radio up to very-high-energy (VHE) gamma rays. The MAGIC telescopes followed up on optical and high-energy triggers and initiated an observation campaign from August 9th till September 1st. RS ...Conference Paper -
The broadband 3-year monitoring of the blazar 1ES1959+650: a SED analysis of the low state
(2023)PoS: Proceedings of Science ~ 38th International Cosmic Ray ConferenceThe Spectral Energy Distribution (SED) of blazars consists of two components. The low-energy bump is interpreted as synchrotron radiation from accelerated electrons, while the high-energy one is produced via inverse Compton scattering of the electrons by lower-energy photons. In the leptonic model interpretation, the latter comes either from the synchrotron radiation produced by the same population of electrons (Synchrotron Self-Compton, ...Conference Paper -
Constraints on VHE gamma-ray emission of Flat Spectrum Radio Quasars with the MAGIC telescopes
(2023)PoS: Proceedings of Science ~ 38th International Cosmic Ray ConferenceBlazars are a class of active galactic nuclei (AGN) where the relativistic jet is pointed towards the observer. They are powerful sources of non-thermal radiation from radio to Very high energy(VHE) gamma-rays. Flat Spectrum Radio Quasars (FSRQs) are a subclass of blazars where there are broad absorption or emission lines present in the optical spectra.The observed properties of FSRQs are strongly affected by the magnetic field in the ...Conference Paper -
Highlights of Galactic Science with the MAGIC telescopes
(2023)PoS: Proceedings of Science ~ 38th International Cosmic Ray ConferenceThere are several types of Galactic sources that can potentially accelerate charged particles up to GeV and TeV energies. These accelerated particles can produce Very High Energy (E>100 GeV) gamma-ray emission through different non-thermal processes such as inverse Compton scattering of ambient photon fields by accelerated electrons or pion decay after proton-proton collisions. Here we present highlight results of observations with the ...Conference Paper -
Multiwavelength study of GRB 201216C using the sub-TeV emission detected by MAGIC
(2023)PoS: Proceedings of Science ~ 38th International Cosmic Ray ConferenceRecently, several gamma-ray bursts (GRBs) have been detected in the very-high-energy (VHE) gamma-ray energy range by ground-based gamma-ray experiments such as MAGIC, H.E.S.S., and LHASSO. For some GRBs, the VHE emission is consistent with synchrotron self-Compton (SSC) emission from high-energy electrons accelerated in the forward shock of the relativistic jet. However, more statistics are needed to further constrain the emission models. ...Conference Paper -
Defining the data legacy of the MAGIC telescopes: adopting a standardised data format and open-source analysis tools
(2023)PoS: Proceedings of Science ~ 38th International Cosmic Ray ConferenceVery-high-energy (VHE, E>100GeV) gamma-ray telescopes have traditionally conducted science with proprietary data and software. After two decades of operations, they have accumulated thousands of hours of observations whose full scientific exploitation cannot be accomplished by the restricted group of scientists operating these instruments. The advent of a new generation of open gamma-ray observatories and, at the same time, the forthcoming ...Conference Paper -
Dark matter searches in dwarf spheroidal galaxies with the Cherenkov Telescope Array
(2023)PoS: Proceedings of Science ~ 38th International Cosmic Ray ConferenceDark matter (DM) is one of the major components in the Universe. However, at present its existence is still only inferred through indirect astronomical observations. DM particles can annihilate or decay, producing final-state Standard Model pairs that subsequently annihilate into high-energy γ-rays. The dwarf spheroidal galaxies (dSphs) in the Milky Way DM halo have long been considered optimal targets to search for annihilating DM ...Conference Paper
