A Large and Variable Leading Tail of Helium in a Hot Saturn Undergoing Runaway Inflation

Posted by klaurent MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Michael Gully-Santiago, Caroline V. Morley, Jessica Luna, Morgan MacLeod, Antonija Oklopčić | Summary: Atmospheric escape shapes the fate of exoplanets, with statistical evidence for transformative mass loss imprinted across the mass-radius-insolation distribution. Here we present transit spectroscopy of the highly irradiated, low-gravity, inflated hot Saturn HAT-P-67 b. […]

Red Supergiant Candidates for Multimessenger Monitoring of the Next Galactic Supernova

Posted by klaurent Tokyo

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Sarah Healy, Shunsaku Horiuchi, Marta Colomer Molla, Dan Milisavljevic, Jeff Tseng | Summary: We compile a catalog of 598 highly probable and 79 likely red supergiants (RSGs) of the Milky Way, which represents the largest list of Galactic RSG candidates to date. We matched distances measured by […]

JADES: deep spectroscopy of a low-mass galaxy at redshift 2.3 quenched by environment

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Lester Sandles, Francesco D’Eugenio, Jakob M. Helton, Roberto Maiolino, Kevin Hainline | Summary: We report the discovery of a quiescent galaxy at $z=2.34$ with a stellar mass of only $M_star = 9.5^{+1.8}_{-1.2} times 10^{8} mathrm{M}_odot$, based on deep JWST/NIRSpec spectroscopy. This is the least massive quiescent galaxy […]

SIMPLE: Simple Intensity Map Producer for Line Emission

Posted by klaurent Tokyo

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Maja Lujan Niemeyer, José Luis Bernal, Eiichiro Komatsu, , | Summary: We present the Simple Intensity Map Producer for Line Emission (SIMPLE), a public code to quickly simulate mock line-intensity maps, and an analytical framework to model intensity maps including observational effects. SIMPLE can be applied to […]

Changing-look Active Galactic Nuclei from the Dark Energy Spectroscopic Instrument. I.Sample from the Early Data

Posted by klaurent Peking

Kavli Affiliate: Linhua Jiang | First 5 Authors: Wei-Jian Guo, Hu Zou, Victoria Anne Fawcett, Rebecca Canning, Stephanie Juneau | Summary: Changing-look Active Galactic Nuclei (CL AGN) can be generally confirmed by the emergence (turn-on) or disappearance (turn-off) of broad emission lines, associated with a transient timescale (about $100sim5000$ days) that is much shorter than […]

Entanglement Suppression, Enhanced Symmetry and a Standard-Model-like Higgs Boson

Posted by Chicago

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Ian Low, Carlos E. M. Wagner, Ming-Lei Xiao, | Summary: We study information-theoretic properties of scalar models containing two Higgs doublets $Phi_a$, where $a=1,2$ is the flavor quantum number. Considering the 2-to-2 scattering $Phi_a Phi_b to Phi_c Phi_d$ as a two-qubit system in the flavor […]
