Little Red Dots: an abundant population of faint AGN at z~5 revealed by the EIGER and FRESCO JWST surveys

Posted by dbos MIT

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Jorryt Matthee, Rohan P. Naidu, Gabriel Brammer, John Chisholm, Anna-Christina Eilers | Summary: Characterising the prevalence and properties of faint active galactic nuclei (AGN) in the early Universe is key for understanding the formation of supermassive black holes (SMBHs) and determining their role in cosmic reionization. […]

The need for focused, hard X-ray investigations of the Sun

Posted by dbos Stanford

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Lindsay Glesener, Albert Y. Shih, Amir Caspi, Ryan Milligan, Hugh Hudson | Summary: Understanding the nature of energetic particles in the solar atmosphere is one of the most important outstanding problems in heliophysics. Flare-accelerated particles compose a huge fraction of the flare energy budget; they have large […]

TOI-4010: A System of Three Large Short-Period Planets With a Massive Long-Period Companion

Posted by klaurent MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Michelle Kunimoto, Andrew Vanderburg, Chelsea X. Huang, M. Ryleigh Davis, Laura Affer | Summary: We report the confirmation of three exoplanets transiting TOI-4010 (TIC-352682207), a metal-rich K dwarf observed by TESS in Sectors 24, 25, 52, and 58. We confirm these planets with HARPS-N radial velocity observations […]

The Star-forming and Ionizing Properties of Dwarf z~6-9 Galaxies in JADES: Insights on Bursty Star Formation and Ionized Bubble Growth

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Ryan Endsley, Daniel P. Stark, Lily Whitler, Michael W. Topping, Benjamin D. Johnson | Summary: Reionization is thought to be driven by faint star-forming galaxies, but characterizing this population has long remained very challenging. Here we utilize deep nine-band NIRCam imaging from JADES to study the star-forming […]

Online Multi-Contact Receding Horizon Planning via Value Function Approximation

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Jiayi Wang, Sanghyun Kim, Teguh Santoso Lembono, Wenqian Du, Jaehyun Shim | Summary: Planning multi-contact motions in a receding horizon fashion requires a value function to guide the planning with respect to the future, e.g., building momentum to traverse large obstacles. Traditionally, the value function is approximated […]

A Tight Correlation Between Millimeter and X-ray Emission in Accreting Massive Black Holes from <100 Milliarcsecond-resolution ALMA Observations

Posted by klaurent Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Claudio Ricci, Chin-Shin Chang, Taiki Kawamuro, George Privon, Richard Mushotzky | Summary: Recent studies have proposed that the nuclear millimeter continuum emission observed in nearby active galactic nuclei (AGN) could be created by the same population of electrons that gives rise to the X-ray emission that is […]

JADES: The production and escape of ionizing photons from faint Lyman-alpha emitters in the epoch of reionization

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Aayush Saxena, Andrew J. Bunker, Gareth C. Jones, Daniel P. Stark, Alex J. Cameron | Summary: We present the properties of 17 faint Ly$alpha$ emitting galaxies (LAEs) at $z>5.8$ from the JWST Advanced Deep Extragalactic Survey (JADES) in the Hubble Ultra Deep Field/GOODS-S. These LAEs span a […]
