Circumnuclear Dust in Luminous Early-Type Galaxies — I. Sample Properties and Stellar Luminosity Models

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jared R. Davidson, Benjamin D. Boizelle, Jonelle L. Walsh, Aaron J. Barth, Emma Rasmussen | Summary: Dusty circumnuclear disks (CNDs) in luminous early-type galaxies (ETGs) show regular, dynamically cold molecular gas kinematics. For a growing number of ETGs, Atacama Large Millimeter/sub-millimeter Array (ALMA) CO imaging and […]

Rising from the ashes: evidence of old stellar populations and rejuvenation events in the very early Universe

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Callum Witten, William McClymont, Nicolas Laporte, Guido Roberts-Borsani, Debora Sijacki | Summary: While JWST has observed galaxies assembling as early as $zsim14$, evidence of galaxies with significant old stellar populations in the Epoch of Reionisation (EoR) — the descendants of these earliest galaxies — are few and […]

The discovery of a nearby 421~s transient with CHIME/FRB/Pulsar

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Fengqiu Adam Dong, Tracy Clarke, Alice P. Curtin, Ajay Kumar, Ingrid Stairs | Summary: Neutron stars and white dwarfs are both dense remnants of post-main-sequence stars. Pulsars, magnetars and strongly magnetised white dwarfs have all been seen to been observed to exhibit coherent, pulsed radio emission […]

Unraveling the role of merger histories in the population of Insitu stars: linking IllustrisTNG cosmological simulation to H3 survey

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Razieh Emami, Lars Hernquist, Randall Smith, James F. Steiner, Grant Tremblay | Summary: We undertake a comprehensive investigation into the distribution of insitu stars within Milky Way-like galaxies, leveraging TNG50 simulations and comparing their predictions with data from the H3 survey. Our analysis reveals that 28% of […]
