PublicationForeground Contributions to 0.2-2° CMB Anisotropies
We examine the extent to which galactic and extragalactic foregrounds can hamper the detection of primordial Cosmic Microwave background (CMB) anisotropies. We...

PublicationImproved CMB anisotropy constraints on primordial magnetic fields from the post-recombination ionization history
We investigate the impact of a stochastic background of primordial magnetic fields (PMF) generated before recombination on the ionization history of the...

PublicationMAGIC observations of the February 2014 flare of 1ES 1011+496 and ensuing constraint of the EBL density
Context. During February-March 2014, the MAGIC telescopes observed the high-frequency peaked BL Lac 1ES 1011+496 (z = 0.212) in flaring state at very-high...

PublicationMore out of less: an excess integrated Sachs-Wolfe signal from supervoids mapped out by the Dark Energy Survey
The largest structures in the cosmic web probe the dynamical nature of dark energy through their integrated Sachs-Wolfe imprints. In the strength of the signal...
