Turning AGN Bubbles into Radio Relics with Sloshing: Modeling CR Transport with Realistic Physics

open access: yesGalaxies, 2021
Radio relics are arc-like synchrotron sources at the periphery of galaxy clusters, produced by cosmic-ray electrons in a μG magnetic field, which are believed to have been (re-)accelerated by merger shock fronts.

Physics of Cosmic Masers [PDF]

open access: yesSymposium - International Astronomical Union, 1988
Natural masers, which emit powerful narrow-band radiation in molecular microwave lines, were discovered about 20 years ago. They draw the astrophysicist's attention in two ways: 1) as a unique physical phenomenon and 2) as very informative probes of physical conditions in those astrophysical objects (very young and very old stars) with which they are ...

High resolution muon tracking with resistive plate chambers [PDF]

open access: yes, 2012
Following their introduction in the physics community in the early '80s the use of Resistive Plate Chambers (RPCs) as charged particles detectors has constantly increased. Low cost per unit area, good time resolution and easy of operation are some of the

CMB as a Probe of New Physics and Old Times [PDF]

open access: yes, 2013
Cosmic birefringence (CB)---a rotation of photon-polarization plane in vacuum---is a generic signature of new scalar fields that could provide dark energy. Previously, WMAP observations excluded a uniform CB-rotation angle larger than a degree.
