A Disintegrating Rocky Planet with Prominent Comet-like Tails Around a Bright Star

Kavli Affiliate: Avi Shporer | First 5 Authors: Marc Hon, Saul Rappaport, Avi Shporer, Andrew Vanderburg, Karen A. Collins | Summary: We report the discovery of BD+05$,$4868$,$Ab, a transiting exoplanet orbiting a bright ($V=10.16$) K-dwarf (TIC 466376085) with a period of 1.27 days. Observations from NASA’s Transiting Exoplanet Survey Satellite (TESS) reveal variable transit depths […]

The impact of the redshift-dependent selection effect of halos on the redshift-space power spectrum

Kavli Affiliate: Masahiro Takada | First 5 Authors: Kanmi Nose, Masahiro Takada, Ryo Terasawa, , | Summary: In a wide-area spectroscopic survey of galaxies, it is nearly impossible to obtain a homogeneous sample of galaxies with respect to galaxy properties such as stellar mass and host halo mass across a range of redshifts. Despite the […]

How to Minimize the Decoherence Caused by Black Holes

Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Jonah Kudler-Flam, Gautam Satishchandran, Robert M. Wald, | Summary: We consider an experimentalist, Alice, who creates a quantum superposition of a charged or massive body outside of a black hole (or, more generally, in the presence of a Killing horizon). It was previously […]
