Combined search in dwarf spheroidal galaxies for branon dark matter annihilation signatures with the MAGIC Telescopes
T. Miener, D. Nieto, V. Gammaldi +2
One of the most pressing questions for modern physics is the nature of dark matter (DM). Several efforts have been made to model this elusive kind of matter. The largest fraction o…
A search for dark matter among Fermi-LAT unidentified sources with systematic features in Machine Learning
V. Gammaldi, B. Zaldívar, M. A. Sánchez-Conde +1
Around one third of the point-like sources in the Fermi-LAT catalogs remain as unidentified sources (unIDs) today. Indeed, these unIDs lack a clear, univocal association with a kno…
Constraining branon dark matter from observations of the dwarf spheroidal galaxies with the MAGIC telescopes
Tjark Miener, Daniel Nieto, Viviana Gammaldi +2
We present the first branon dark matter (DM) search in the very high-energy gamma-ray band with observations of the dwarf spheroidal galaxy Segue~1 carried out by the Major Atmosph…
Search for new cosmic-ray acceleration sites within the 4FGL catalog Galactic plane sources
LAT Collaboration, S. Abdollahi, F. Acero +117
Cosmic rays are mostly composed of protons accelerated to relativistic speeds. When those protons encounter interstellar material, they produce neutral pions which in turn decay in…
A Gamma-ray Pulsar Timing Array Constrains the Nanohertz Gravitational Wave Background
M. Ajello, W. B. Atwood, L. Baldini +129
After large galaxies merge, their central supermassive black holes are expected to form binary systems whose orbital motion generates a gravitational wave background (GWB) at nanoh…
Constraining branon dark matter from observations of the Segue 1 dwarf spheroidal galaxy with the MAGIC telescopes
Tjark Miener, Daniel Nieto, Viviana Gammaldi +2
We present the first search for signatures of brane-world extra-dimensional dark matter (DM) in the very-high-energy gamma-ray band by scrutinizing observations of the dwarf sphero…
