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 work, we study the sensitivity of the Fermi-LAT to extended subhalos using simulated data based on a realistic sky mode ...

Antarctic penguins’ guano represents a complex mixture of nutrients and chemical compounds. A large amount of guano produced during the breeding season can flow into seawater, near the colonies, altering the chemical balance of coastal environments. However, information on how guano input may alter ...

Penguins are emblematic inhabitants of the Antarctic continent and play a significant role in the biogeochemical cycles of the Southern Ocean by transferring essential nutrients to marine ecosystems via guano production. Despite their ecological importance, the contribution of penguin guano to carbo ...

Gamma-ray observations have long been used to constrain the properties of dark matter (DM), with a strong focus on weakly interacting massive particles annihilating through velocity-independent processes. However, in the absence of clear-cut observational evidence for the simplest candidates, the in ...

Indirect searches with gamma rays set strong constraints on the properties of self-annihilating dark matter particle candidates. Observations of dwarf galaxies and galaxy clusters are especially interesting. Here we revisit the calculation of the annihilation flux by considering a velocity-dependent ...

Abstract
As searches for thermal and self-annihilating dark matter (DM) intensify, it becomes
crucial to include as many relevant physical processes and ingredients as possible to refine
signal predictions, in particular those which directly relate to the intimate propertie ...

We analyze 11 years of Fermi-Large Area Telescope (LAT) data corresponding to the sky regions of seven dwarf irregular (dIrr) galaxies. DIrrs are dark matter (DM)-dominated systems, proposed as interesting targets for the indirect search of DM with gamma rays. The galaxies represent interesting case ...

In these proceedings we highlight the main results about dark matter (DM) search in dwarf irregular galaxies with the \textit{Fermi} Large Area Telescope. We analyze 11 years of Fermi-LAT data corresponding to the sky regions of 7 dwarf irregular (dIrr) galaxies. DIrrs are DM dominated systems, rece ...
