On the dark matter content of ultra-diffuse galaxies

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Andrey Kravtsov, , , , | Summary: I compare the dark matter content within stellar half-mass radius expected in a $Lambda$CDM-based galaxy formation model with existing observational estimates for the observed dwarf satellites of the Milky Way and ultra-diffuse galaxies (UDGs). The model reproduces the main properties […]

The Precursor Small Aperture Telescope (PreSAT) CMB polarimeter

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Matthew A. Petroff, Zeeshan Ahmed, James J. Bock, Marion Dierickx, Sofia Fatigoni | Summary: The search for the polarized imprint of primordial gravitational waves in the cosmic microwave background (CMB) as direct evidence of cosmic inflation requires exquisite sensitivity and control over systematics. The next-generation CMB-S4 project […]

A surprising excess of radio emission in extremely stable quasars: a unique clue to jet launching?

Kavli Affiliate: Feng Yuan | First 5 Authors: Wen-Yong Kang, Jun-Xian Wang, Zhen-Yi Cai, Hao-Chen Wang, Wen-Ke Ren | Summary: Quasars are generally divided into jetted radio-loud and non-jetted radio-quiet ones, but why only 10% quasars are radio loud has been puzzling for decades. Other than jet-induced-phenomena, black hole mass, or Eddington ratio, prominent difference […]
