Stochastic Streets: A Walk Through Random LLM Address Generation in four European Cities
Tairan Fu, David Campo-Nazareno, Javier Coronado-Blázquez +3
Large Language Models (LLMs) are capable of solving complex math problems or answer difficult questions on almost any topic, but can they generate random street addresses for Europ…
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…
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…
Spatial extension of dark subhalos as seen by Fermi-LAT and implications for WIMP constraints
J. Coronado-Blazquez, M. Sanchez-Conde, J. Perez-Romero +1
Spatial extension has been hailed as a "smoking gun" in the gamma-ray search of dark galactic subhalos, which would appear as unidentified sources for gamma-ray telescopes. In this…
Dark Matter search in dwarf irregular galaxies with the Fermi Large Area Telescope
V. Gammaldi, J. Pérez-Romero, J. Coronado-Blázquez +4
We analyze 11 years of Fermi-LAT data corresponding to the sky regions of 7 dwarf irregular (dIrr) galaxies. DIrrs are dark matter (DM) dominated systems, proposed as interesting t…
Sensitivity of the Cherenkov Telescope Array to dark subhalos
Javier Coronado-Blázquez, Michele Doro, Miguel A. Sánchez-Conde +1
In this work, we study the potential of the Cherenkov Telescope Array (CTA) for the detection of Galactic dark matter (DM) subhalos. We focus on low-mass subhalos that do not host…
Sensitivity of the Cherenkov Telescope Array for probing cosmology and fundamental physics with gamma-ray propagation
The Cherenkov Telescope Array Consortium, :, H. Abdalla +496
The Cherenkov Telescope Array (CTA), the new-generation ground-based observatory for -ray astronomy, provides unique capabilities to address significant open questions in astrop…
Sensitivity of the Cherenkov Telescope Array to a dark matter signal from the Galactic centre
The Cherenkov Telescope Array Consortium, :, A. Acharyya +449
We provide an updated assessment of the power of the Cherenkov Telescope Array (CTA) to search for thermally produced dark matter at the TeV scale, via the associated gamma-ray sig…
Fermi Large Area Telescope Fourth Source Catalog Data Release 2
J. Ballet, T. H. Burnett, S. W. Digel +1
We present an incremental version (4FGL-DR2, for Data Release 2) of the fourth Fermi-LAT catalog of gamma-ray sources. Based on the first ten years of science data in the energy ra…
Constraints to dark matter annihilation from high-latitude HAWC unidentified sources
Javier Coronado-Blazquez, Miguel A. Sanchez-Conde
The CDM cosmological framework predicts the existence of thousands of subhalos in our own Galaxy not massive enough to retain baryons and become visible. Yet, some of them may s…
Spectral and spatial analysis of the dark matter subhalo candidates among Fermi Large Area Telescope unidentified sources
Javier Coronado-Blázquez, Miguel A. Sánchez-Conde, Mattia Di Mauro +5
Fermi-LAT unidentified sources (unIDs) have proven to be compelling targets for performing indirect dark matter (DM) searches. In a previous work, we found that among the 1235 unID…
Unidentified Gamma-ray Sources as Targets for Indirect Dark Matter Detection with the Fermi-Large Area Telescope
Javier Coronado-Blazquez, Miguel A. Sanchez-Conde, Alberto Dominguez +5
One of the predictions of the CDM cosmological framework is the hierarchical formation of structure, giving rise to dark matter (DM) halos and subhalos. When the latter are mass…
X-ray and gamma-ray limits on the primordial black hole abundance from Hawking radiation
Guillermo Ballesteros, Javier Coronado-Blázquez, Daniele Gaggero
The non-observation of Hawking radiation from primordial black holes of g sets a conservative strong bound on their cosmological abundance. We revisit this bound and show…
Fermi Large Area Telescope Fourth Source Catalog
LAT collaboration
We present the fourth Fermi Large Area Telescope catalog (4FGL) of gamma-ray sources. Based on the first eight years of science data from the Fermi Gamma-ray Space Telescope missio…
