The white-light superflares from cool stars in GWAC triggers

Kavli Affiliate: Jing Wang | First 5 Authors: Guang-Wei Li, Liang Wang, Hai-Long Yuan, Li-Ping Xin, Jing Wang | Summary: M-type stars are the ones that flare most frequently, but how big their maximum flare energy can reach is still unknown. We present 163 flares from 162 individual M2 through L1-type stars that triggered the […]

Spectroastrometry and Reverberation Mapping (SARM) of Active Galactic Nuclei. I. The H$β$ Broad-line Region Structure and Black Hole Mass of Five Quasars

Kavli Affiliate: Luis C. Ho | First 5 Authors: Yan-Rong Li, Chen Hu, Zhu-Heng Yao, Yong-Jie Chen, Hua-Rui Bai | Summary: We conduct a reverberation mapping (RM) campaign to spectroscopically monitor a sample of selected bright active galactic nuclei with large anticipated broad-line region (BLR) sizes adequate for spectroastrometric observations by the GRAVITY instrument on […]

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 […]
