COOL-LAMPS VIII: Known wide-separation lensed quasars and their host galaxies reveal a lack of evolution in $M_{rm{BH}}/M_star$ since $zsim 3$

Posted by dbos Chicago

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Aidan P. Cloonan, Gourav Khullar, Kate A. Napier, Michael D. Gladders, Håkon Dahle | Summary: Wide-separation lensed quasars (WSLQs) are a rare class of strongly lensed quasars, magnified by foreground massive galaxy clusters, with typically large magnifications of the multiple quasar images. They are a relatively […]

JADES Ultra-red Flattened Objects: Morphologies and Spatial Gradients in Color and Stellar Populations

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Justus L. Gibson, Erica Nelson, Christina C. Williams, Sedona H. Price, Katherine E. Whitaker | Summary: One of the more surprising findings after the first year of JWST observations is the large number of spatially extended galaxies (ultra-red flattened objects, or UFOs) among the optically-faint galaxy population […]

Cosmological Simulations of Stellar Halos with Gaia Sausage-Enceladus Analogues: Two Sausages, One Bun?

Posted by dbos MIT

Kavli Affiliate: Lina Necib | First 5 Authors: Dylan Folsom, Mariangela Lisanti, Lina Necib, Danny Horta, Mark Vogelsberger | Summary: Observations of the Milky Way’s stellar halo find that it is predominantly comprised of a radially-biased population of stars, dubbed the Gaia Sausage–Enceladus, or GSE. These stars are thought to be debris from dwarf galaxy […]

The RAdio Galaxy Environment Reference Survey (RAGERS): Evidence of an anisotropic distribution of submillimeter galaxies in the 4C 23.56 protocluster at z=2.48

Posted by dbos Peking

Kavli Affiliate: Ran Wang | First 5 Authors: Dazhi Zhou, Thomas R. Greve, Bitten Gullberg, Minju M. Lee, Luca Di Mascolo | Summary: High-redshift radio(-loud) galaxies (H$z$RGs) are massive galaxies with powerful radio-loud active galactic nuclei (AGNs) and serve as beacons for protocluster identification. However, the interplay between H$z$RGs and the large-scale environment remains unclear. […]

EDEN: Exploring Disks Embedded in N-body simulations of Milky-Way-mass halos from Symphony

Posted by dbos Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Yunchong Wang, Philip Mansfield, Ethan O. Nadler, Elise Darragh-Ford, Risa H. Wechsler | Summary: We investigate the impact of galactic disks on the tidal stripping of cold dark matter subhalos within Milky Way (MW)-mass halos ($M_{rm vir}sim 10^{12}mathrm{M_{odot}}$) using a new simulation suite, EDEN. By re-simulating […]
