After introducing the concepts of axions and axion-like-particles (ALPs) and their signals, true axions which can be either much heavier or much lighter than the canonical axion will be discussed. The implications for dark matter, neutron stars and gravitational waves searches will also be addressed.
Galaxies and the dark matter halos in which they reside are intrinsically connected. That relationship holds information about key processes in galaxy and structure formation. In this talk, I will consider how the galaxy-halo connection depends on position within the cosmic web - the familiar decomposition of large-scale structure in filaments
Beyond the Concordance Model with galaxy cluster mass profiles
I present the recent results obtained using the updated version of MG-MAMPOSSt, a code that constrains modified gravity (MG) models viable at cosmological scales using determination of galaxy cluster mass profiles with kinematics and lensing analyses. I will discuss limitations and future developments of this method in view of upcoming imaging and
Observing the polarized microwave sky: 10 years of the QUIJOTE experiment
I will review the status of the QUIJOTE (Q-U-I JOint TEnerife) experiment, a project led from the IAC with the aim of characterising the polarisation of the Cosmic Microwave Background (CMB) and other galactic or extragalactic physical processes that emit in microwaves in the frequency range 10-42GHz, and at large angular scales (1 degree
