Kavli Affiliate: George Ricker | First 5 Authors: Charles Cadieux, René Doyon, Mykhaylo Plotnykov, Guillaume Hébrard, Farbod Jahandar | Summary: Exploring the properties of exoplanets near or inside the radius valley provides insights on the transition from the rocky super-Earths to the larger, hydrogen-rich atmosphere mini-Neptunes. Here, we report the discovery of TOI-1452 b, a […]
Kavli Affiliate: Roland Vanderspek | First 5 Authors: Carina M. Persson, Iskra Y. Georgieva, Davide Gandolfi, Lorena Acuña, Artem Aguichine | Summary: Highly irradiated planets in the hot Neptune desert are usually either small (R < 2 Rearth) and rocky or they are gas giants with radii of >1 Rjup. Here, we report on the […]
Kavli Affiliate: Sara Seager | First 5 Authors: Rachana Agrawal, Weston P. Buchanan, Archit Arora, Athul P. Girija, Maxim de Jong | Summary: Venus is known for its extreme surface temperature and its sulfuric acid clouds. But the cloud layers on Venus have similar temperature and pressure conditions to those on the surface of Earth […]
Kavli Affiliate: Sara Seager | First 5 Authors: Weston P. Buchanan, Maxim de Jong, Rachana Agrawal, Janusz J. Petkowski, Archit Arora | Summary: Mounting evidence of chemical disequilibria in the Venusian atmosphere has heightened interest in the search for life within the planet’s cloud decks. Balloon systems are currently considered to be the superior class […]
Kavli Affiliate: Sara Seager | First 5 Authors: Sara Seager, Janusz J. Petkowski, Christopher E. Carr, David H. Grinspoon, Bethany L. Ehlmann | Summary: Finding evidence of extraterrestrial life would be one of the most profound scientific discoveries ever made, advancing humanity into a new epoch of cosmic awareness. The Venus Life Finder (VLF) missions […]
Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Peter Bult, Diego Altamirano, Zaven Arzoumanian, Deepto Chakrabarty, Jérôme Chenevez | Summary: We present the discovery of 528.6 Hz pulsations in the new X-ray transient MAXI J1816-195. Using NICER, we observed the first recorded transient outburst from the neutron star low-mass X-ray binary MAXI J1816-195 over a […]
Kavli Affiliate: Erin Kara | First 5 Authors: Ruancun Li, Luis C. Ho, Claudio Ricci, Benny Trakhtenbrot, Iair Arcavi | Summary: Changing-look active galactic nuclei (AGNs) present an important laboratory to understand the origin and physical properties of the broad-line region (BLR). We investigate follow-up optical spectroscopy spanning $sim 500$ days after the outburst of […]
Kavli Affiliate: Richard Foster | First 5 Authors: Catherine E. Grant, Eric D. Miller, Marshall W. Bautz, Richard Foster, Ralph P. Kraft | Summary: A science goal of many future X-ray observatories is mapping the cosmic web through deep exposures of faint diffuse sources. Such observations require low background and the best possible knowledge of […]

Kavli Affiliate: Marshall W. Bautz | First 5 Authors: Tanmoy Chattopadhyay, Sven Herrmann, Peter Orel, R. G. Morris, Daniel R. Wilkins | Summary: Single electron Sensitive Read Out (SiSeRO) is a novel on-chip charge detector output stage for charge-coupled device (CCD) image sensors. Developed at MIT Lincoln Laboratory, this technology uses a p-MOSFET transistor with […]
