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 ...

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 ...

In the past decade, the observations of diffuse radio synchrotron emission toward galaxy clusters revealed cosmic-ray (CR) electrons and magnetic fields on megaparsec scales. However, their origin remains poorly understood to date, and several models have been discussed in the literature. CR protons ...

The nature of dark matter is a longstanding enigma of physics; it may consist of particles beyond the Standard Model that are still elusive to experiments. Among indirect searchtechniques, which look for stable products from the annihilation or decay of dark matter particles, or from axions coupling ...

V diplomskem delu sem opisal GNSS tehnologijo, ki je nepogrešljivi člen pri raznoraznih geodetskih storitvah. Izpostavil sem ključne satelitske sisteme, njihovo sestavo in delovanje, ter predstavil proces nastajanja geodetskega načrta z uporabo GNSS tehnologije. Na primeru sem prikazal izmero točke ...
