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

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

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

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

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

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 […]

Inside the bubble: exploring the environments of reionisation-era Lyman-$α$ emitting galaxies with JADES and FRESCO

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Joris Witstok, Renske Smit, Aayush Saxena, Gareth C. Jones, Jakob M. Helton | Summary: We present a study of the environments of 17 Lyman-$alpha$ (Ly$alpha$) emitting galaxies (LAEs) in the reionisation era ($5.8 < z < 8$) identified by JWST/NIRSpec as part of the JWST Advanced Deep […]

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

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 […]

Spectral variability of photospheric radiation due to faculae II: Facular contrasts for cool main-sequence stars

Kavli Affiliate: Robert Cameron | First 5 Authors: Charlotte M. Norris, Yvonne C. Unruh, Veronika Witzke, Sami K. Solanki, Natalie A. Krivova | Summary: Magnetic features on the surface of stars, such as spots and faculae, cause stellar spectral variability on time-scales of days and longer. For stars other than the Sun, the spectral signatures […]

Two Warm Neptunes transiting HIP 9618 revealed by TESS & Cheops

Kavli Affiliate: Robert F. Goeke | First 5 Authors: Hugh P. Osborn, Grzegorz Nowak, Guillaume Hébrard, Thomas Masseron, J. Lillo-Box | Summary: HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright ($G=9.0$ mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of $3.9 pm 0.044$ $R_oplus$ (HIP 9618 […]
