Kavli Affiliate: Christopher J. Burke | First 5 Authors: Fei Dai, Kevin C. Schlaufman, Henrique Reggiani, Luke Bouma, Andrew W. Howard | Summary: We report the discovery and Doppler mass measurement of a 7.4-day 2.3-$R_oplus$ mini-Neptune around a metal-poor K dwarf BD+29 2654 (TOI-2018). Based on a high-resolution Keck/HIRES spectrum, the Gaia parallax, and multi-wavelength […]
Kavli Affiliate: George Ricker | First 5 Authors: Manan Agarwal, Jay Alameda, Jeroen Audenaert, Will Benoit, Damon Beveridge | Summary: Modern large-scale physics experiments create datasets with sizes and streaming rates that can exceed those from industry leaders such as Google Cloud and Netflix. Fully processing these datasets requires both sufficient compute power and efficient […]

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. […]

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 […]
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 […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Alexander Venner, Simon Blouin, Antoine Bédard, Andrew Vanderburg, | Summary: The observational signature of core crystallization of white dwarfs has recently been discovered. However, the magnitude of the crystallization-powered cooling delay required to match observed white dwarfs is larger than predicted by conventional models, requiring additional mechanisms […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Victor Doroshenko, Juri Poutanen, Jeremy Heyl, Sergey S. Tsygankov, Ilaria Caiazzo | Summary: We report on Imaging X-ray polarimetry explorer (IXPE) observations of the Be-transient X-ray pulsar LS V +44 17/RX J0440.9+4431 made at two luminosity levels during the giant outburst in January–February 2023. Considering the […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: William Lake, Smadar Naoz, Federico Marinacci, Blakesley Burkhart, Mark Vogelsberger | Summary: The formation mechanism of globular clusters (GCs) has long been debated by astronomers. It was recently proposed that Supersonically Induced Gas Objects (SIGOs), which formed in the early Universe due to the supersonic relative motion […]
