Probing Magnetic Fields In and Around Galaxies Near and Far
S. A. Mao, Rainer Beck, Aritra Basu +14
In order to understand the magnetization of galaxies and the role of magnetic fields in feedback processes that govern star formation and galaxy evolution, it is essential to have…
Unraveling the Imprints of Fluctuation-dynamo on the Intracluster Medium with the SKA
Aritra Basu, Sharanya Sur, Nadia Biava +1
Studying the morphology and coherence scale of the magnetic fields in synchrotron emitting halos of galaxy clusters through detection of polarized synchrotron emission is important…
Probing the Fundamental Nature of Particle Dark Matter
Marco Regis, Aritra Basu, Geoff Beck +7
Understanding the fundamental nature of dark matter (DM) is one of the most significant scientific challenges of our time. A compelling hypothesis is that DM consists of a new, yet…
Small-scale Magnetic Fields in the Milky Way and Nearby Galaxies
Yik Ki Ma, Amit Seta, Aritra Basu +13
Magnetic fields in galaxies span decades in physical scale, from the coherent magnetic fields on galactic scales (> kpc) to the random magnetic fields from 100 pc to the resistive…
MEDUSA I. Tracing magnetic field structures in tidal arms of the dwarf-dwarf merger NGC 1487
Sam Taziaux, Aritra Basu, Samata Das +11
Dwarf galaxies are important laboratories for studying cosmic magnetism because they can maintain strong magnetic fields via the action of turbulent dynamo despite their low mass a…
Constraining Axion-like Particles through Multi-epoch Monitoring of Strong Gravitational Lenses
Shivani Deshmukh, Aritra Basu, Dominik J. Schwarz +2
We present new constraints on ultralight axion-like particles (ALPs) through multi-epoch measurements of differential birefringence induced due to a coupling () between th…
