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 […]

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Patrick Obin Sturm, Saketh Bharadwaj, Sam Silva, Max Tegmark | Summary: Discovering conservation laws for a given dynamical system is important but challenging. In a theorist setup (differential equations and basis functions are both known), we propose the Sparse Invariant Detector (SID), an algorithm that […]

Kavli Affiliate: David A. Principe | First 5 Authors: Pedro Henrique Nogueira, Alice Zurlo, Sebastián Pérez, Camilo González-Ruilova, Lucas A. Cieza | Summary: Episodic accretion is a low-mass pre-main sequence phenomenon characterized by sudden outbursts of enhanced accretion. These objects are classified into two: protostars with elevated levels of accretion that lasts for decades or […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Valery F. Suleimanov, Sofia V. Forsblom, Sergey S. Tsygankov, Juri Poutanen, Victor Doroshenko | Summary: The phase- and energy-resolved polarization measurements of accreting X-ray pulsars (XRPs) allow us to test different theoretical models of their emission, and they also provide an avenue to determine the emission […]

Kavli Affiliate: Lisa Barsotti | First 5 Authors: Chris Whittle, Ge Yang, Matthew Evans, Lisa Barsotti, | Summary: Machine learning has become an effective tool for processing the extensive data sets produced by large physics experiments. Gravitational-wave detectors are now listening to the universe with quantum-enhanced sensitivity, accomplished with the injection of squeezed vacuum states. […]
