Migration and Evolution of giant ExoPlanets (MEEP) I: Nine Newly Confirmed Hot Jupiters from the TESS Mission

Kavli Affiliate: Avi Shporer | First 5 Authors: Jack Schulte, Joseph E. Rodriguez, Allyson Bieryla, Samuel N. Quinn, Karen A. Collins | Summary: Hot Jupiters were many of the first exoplanets discovered in the 1990s, but in the decades since their discovery, the mysteries surrounding their origins remain. Here, we present nine new hot Jupiters […]

Constraining the clustering and 21-cm signature of radio galaxies at cosmic dawn

Kavli Affiliate: George Efstathiou | First 5 Authors: Sudipta Sikder, Rennan Barkana, Anastasia Fialkov, , | Summary: The efficiency of radio emission is an important unknown parameter of early galaxies at cosmic dawn, as models with high efficiency have been shown to modify the cosmological 21-cm signal substantially, deepening the absorption trough and boosting the […]

JWST-TST High Contrast: Asymmetries, dust populations and hints of a collision in the $β$ Pictoris disk with NIRCam and MIRI

Kavli Affiliate: Sara Seager | First 5 Authors: Isabel Rebollido, Christopher C. Stark, Jens Kammerer, Marshall D. Perrin, Kellen Lawson | Summary: We present the first JWST MIRI and NIRCam observations of the prominent debris disk around Beta Pictoris. Coronagraphic observations in 8 filters spanning from 1.8 to 23~$mu$m provide an unprecedentedly clear view of […]

The Kinematic and Chemical Properties of the Close-in Planet Host Star 8 UMi

Kavli Affiliate: Huawei Zhang | First 5 Authors: Huiling Chen, Yang Huang, Wei Zhu, Timothy C. Beers, Renjing Xie | Summary: A recent study by Hon et al. reported that a close-in planet around the red clump star, 8 UMi, should have been engulfed during the expansion phase of the stellar evolution. They explained the […]

On the Physical Nature of Ly$α$ Transmission Spikes in High Redshift Quasar Spectra

Kavli Affiliate: Nickolay Gnedin | First 5 Authors: Hanjue Zhu, Nickolay Gnedin, Camille Avestruz, , | Summary: We investigate Lyman-alpha (Ly$alpha$) transmission spikes at $5.2 < z < 6.8$ using synthetic quasar spectra from the “Cosmic Reionization On Computers" simulations. We focus on understanding the relationship between these spikes and the properties of the intergalactic […]
