Combined dark matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
Celine Armand, Eric Charles, Mattia di Mauro +13
Cosmological and astrophysical observations suggest that 85\% of the total matter of the Universe is made of Dark Matter (DM). However, its nature remains one of the most challengi…
Particle Acceleration in the Cygnus Superbubble
B. Hona
The Cygnus Cocoon is the first gamma-ray superbubble powered by a massive stellar association, the OB2 association. It was postulated that the combined effects of the stellar winds…
The all-particle cosmic ray energy spectrum measured with HAWC
J. A. Morales-Soto, J. C. Arteaga-Velázquez
Thanks to recent technological development, a new generation of cosmic ray experiments have been developed with more sensitivity to study these particles in the primary energy inte…
Performance of the New FlashCam-based Camera in the 28\,m Telescope of H.E.S.S
Baiyang Bi, Miquel Barcelo, Christian Bauer +23
In October 2019, the central 28 m telescope of the H.E.S.S. experiment has been upgraded with a new camera. The camera is based on the FlashCam design which has been developed in v…
The young massive stellar cluster Westerlund 1 in rays as seen with H.E.S.S
Lars Mohrmann, Andreas Specovius, Romed Rauth +2
Massive stellar clusters have recently been hypothesised as candidates for the acceleration of hadronic cosmic rays up to PeV energies. Previously, the H.E.S.S. Collaboration has r…
Detection of extended TeV emission around the Geminga pulsar with H.E.S.S
A. M. W. Mitchell, S. Caroff, J. Hinton +1
Highly extended gamma-ray emission around the Geminga pulsar was discovered by Milagro and verified by HAWC. Despite many observations with Imaging Atmospheric Cherenkov Telescopes…
Detection of new Extreme BL Lac objects with H.E.S.S. and Swift XRT
Mathieu de Bony de Lavergne, Tomas Bylund, Manuel Meyer +2
Extreme high synchrotron peaked blazars (EHBLs) are amongst the most powerful accelerators found in nature. Usually the synchrotron peak frequency of an EHBL is above Hz…
Astronomy outreach in Namibia: H.E.S.S. and beyond
Hannah Dalgleish, Heike Prokoph, Sylvia Zhu +6
Astronomy plays a major role in the scientific landscape of Namibia. Because of its excellent sky conditions, Namibia is home to ground-based observatories like the High Energy Spe…
Monitoring the radio galaxy M87 with HAWC
T. Capistrán, D. Avila Rojas, M. M. González +2
Studies of radio galaxies at TeV energies are fascinating because their jets are misaligned concerning our sightline. Thus, it provides us with a unique opportunity to study the st…
Use of Machine Learning for gamma/hadron separation with HAWC
T. Capistrán, K. L. Fan, J. T. Linnemann +3
Background showers triggered by hadrons represent over 99.9% of all particles arriving at ground-based gamma-ray observatories. An important stage in the data analysis of these obs…
Horizontal muon track identification with neural networks in HAWC
J. R. Angeles Camacho, H. León Vargas
Nowadays the implementation of artificial neural networks in high-energy physics has obtained excellent results on improving signal detection. In this work we propose to use neural…
