Satellite galaxies experience multiple physical processes when interacting with their host halos, often leading to the quenching of star formation. In the Local Group, satellite quenching has been shown to be highly efficient, affecting most satellites except the most massive ones. While recent surveys are studying Milky Way analogs to assess how representative our Local Group is, the dominant...
The ALICE collaboration has recently reported pi+-K_S femtoscopic correlations in pp collisions[1]. Here we show [2] how they can be well described using existing realistic pi-K interactions obtained from a dispersive analysis of scattering data [3], containing an accurate description of the kappa/K0*(700) resonance pole.

The study of the first galaxies which contributed to the ionization of the universe will become possible with an integral field and multi-object spectrograph like MOSAIC (significant contribution from GUAIX), set to be installed on the 39m Extremely Large Telescope (ELT), currently under construction. As a pilot study for that, a detailed two-dimensional study of the physical properties of a...
The CIEMAT Gamma-Ray Astronomy group works within the MAGIC and CTA-LST collaborations, covering a wide range of activities from hardware development and testing to data analysis and scientific research. This talk will summarize our main contributions and their role in advancing gamma-ray astrophysics.
In order to find Earth-like planets in the habitable zone of M dwarfs, it becomes essential to quantify the stellar noise in the radial velocity (RV) data in order to measure planetary signals. This is why the use of multidimensional Gaussian processes can be a clear evolution towards the study and characterisation of exoplanets and their host stars, this will be done using the pyaneti...
