Kavli Affiliate: Sara Seager | First 5 Authors: William Bains, Janusz J. Petkowski, Sara Seager, , | Summary: Life is a complex, dynamic chemical system that requires a dense fluid solvent in which to take place. A common assumption is that the most likely solvent for life is liquid water, and some researchers argue that […]
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 […]
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 […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Lindsay M. Berkhout, Daniel C. Jacobs, Zuhra Abdurashidova, Tyrone Adams, James E. Aguirre | Summary: This paper presents the design and deployment of the Hydrogen Epoch of Reionization Array (HERA) phase II system. HERA is designed as a staged experiment targeting 21 cm emission measurements of […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Malena Rice, Konstantin Gerbig, Andrew Vanderburg, , | Summary: The current orbital geometries of exoplanet systems offer a fossilized record of the systems’ dynamical histories. A particularly rich set of dynamical mechanisms is available to exoplanets residing in multi-star systems, which may have their evolution shaped by […]
Kavli Affiliate: Eric Miller | First 5 Authors: Arnab Sarkar, Felipe Andrade-Santos, Reinout J. van Weeren, Ralph P. Kraft, Duy N. Hoang | Summary: We present a 368 ks deep Chandra observation of Abell~1240, a binary merging galaxy cluster at a redshift of 0.195 with two Brightest Cluster Galaxies (BCGs) may have passed each other […]
Kavli Affiliate: George R. Ricker | First 5 Authors: Travis S. Metcalfe, Klaus G. Strassmeier, Ilya V. Ilyin, Derek Buzasi, Oleg Kochukhov | Summary: The consistently low activity level of the old solar analog 51 Peg not only facilitated the discovery of the first hot Jupiter, but also led to the suggestion that the star […]
Kavli Affiliate: Sara Seager | First 5 Authors: Maxwell D. Seager, Sara Seager, William Bains, Janusz J. Petkowski, | Summary: Scientists have long speculated about the potential habitability of Venus, not at the 700K surface, but in the cloud layers located at 48-60 km altitudes, where temperatures match those found on Earth’s surface. However, the […]
Kavli Affiliate: Erin Kara | First 5 Authors: Megan Masterson, Kishalay De, Christos Panagiotou, Erin Kara, Iair Arcavi | Summary: Most tidal disruption events (TDEs) are currently found in time-domain optical and soft X-ray surveys, both of which are prone to significant obscuration. The infrared (IR), however, is a powerful probe of dust-enshrouded environments, and […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Nadia Qutob, Razieh Emami, Kung-Yi Su, Randall Smith, Lars Hernquist | Summary: We make an in-depth analysis of different AGN jet models’ signatures, inducing quiescence in galaxies with a halo mass of $10^{12} M_odot$. Three jet models, including cosmic ray-dominant, hot thermal, and precessing kinetic jets, are […]
