After introducing the concepts of axions and axion-like-particles (ALPs) and their signals, true axions which can be either much heavier or muchlighter than the...
The standard cosmological model has been established and its parameters are now measured with unprecedented precision. However, there is a big difference...
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...
I revisit the claim of Dark Energy detection after stacking CMB data on the angular position of voids and superclusters in Sloan Data. I examine the...
We present recent theoretical and empirical results concerning the accuracy of Cepheid distance estimates based on optical and near-infrared (NIR) Period...
Constraints on Ultra-Light Dark Matter from Galactic Rotation Curves
Bosonic ultra-light dark matter (ULDM) in the mass range m ~ $10^{-22} - 10^{-21} \rm eV$ has been invoked as a motivated candidate with new input for the small...
