Wet Compaction to a Blue Nugget: a Critical Phase in Galaxy Evolution

Sharon Lapiner, Avishai Dekel, Jonathan Freundlich, Omri Ginzburg, Fangzhou Jiang | Summary: [[{“value”:”We utilize high-resolution cosmological simulations to reveal that high-redshift galaxies tend to undergo a robust `wet compaction’ event when near a `golden’ stellar mass of $sim 10^{10} M_{odot}$. This is a gaseous shrinkage to a compact star-forming phase, a `blue nugget’ (BN), followed […]

Sidelobe Modeling and Mitigation for a Three Mirror Anastigmat Cosmic Microwave Background Telescope

Kavli Affiliate: John Carlstrom | First 5 Authors: Ian Gullett, Bradford Benson, Robert Besuner, Richard Bihary, John Carlstrom | Summary: Telescopes measuring cosmic microwave background (CMB) polarization on large angular scales require exquisite control of systematic errors to ensure the fidelity of the cosmological results. In particular, far-sidelobe contamination from wide angle scattering is a […]

Clumpy wind studies and the non-detection of cyclotron line in OAO 1657-415

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Pragati Pradhan, Carlo Ferrigno, Biswajit Paul, Enrico Bozzo, Ileyk El Mellah | Summary: Winds of massive stars are suspected to be inhomogeneous (or clumpy), which biases the measures of their mass loss rates. In High Mass X-ray Binaries (HMXBs), the compact object can be used as an […]
