A long-duration superflare on the K giant HD 251108

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Hans Moritz Günther, Dheeraj Pasham, Alexander Binks, Stefan Czesla, Teruaki Enoto | Summary: Many giant stars are magnetically active, which causes rotational variability, chromospheric emission lines, and X-ray emission. Large outbursts in these emission features can set limits on the magnetic field strength and thus constrain the […]

Aemulus $ν$: Precision halo mass functions in w$ν$CDM cosmologies

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Delon Shen, Nickolas Kokron, Joseph DeRose, Jeremy Tinker, Risa H. Wechsler | Summary: Precise and accurate predictions of the halo mass function for cluster mass scales in $wnu{rm CDM}$ cosmologies are crucial for extracting robust and unbiased cosmological information from upcoming galaxy cluster surveys. Here, we […]

First Resolution of Microlensed Images of a Binary-Lens Event

Kavli Affiliate: Subo Dong | First 5 Authors: Zexuan Wu, Subo Dong, A. Mérand, Christopher S. Kochanek, Przemek Mróz | Summary: We resolve the multiple images of the binary-lens microlensing event ASASSN-22av using the GRAVITY instrument of the Very Large Telescope Interferometer (VLTI). The light curves show weak binary-lens perturbations, complicating the analysis, but the […]

Chiral superfluid helium-3 in the quasi-two-dimensional limit

Kavli Affiliate: Jeevak M. Parpia | First 5 Authors: Petri J. Heikkinen, Lev V. Levitin, Xavier Rojas, Angadjit Singh, Nathan Eng | Summary: Anisotropic pair breaking close to surfaces favors the chiral A phase of the superfluid $^3$He over the time-reversal invariant B phase. Confining the superfluid $^3$He into a cavity of height $D$ of […]

Brain state and cortical layer-specific mechanisms underlying perception at threshold

Kavli Affiliate: Anirvan Nandy, John Reynolds | Authors: Mitchell P Morton, Sachira Denagamage, Isabel J Blume, John H Reynolds, Monika P Jadi and Anirvan S Nandy | Summary: Identical stimuli can be perceived or go unnoticed across successive presentations, producing divergent behavioral outcomes despite similarities in sensory input. We sought to understand how fluctuations in […]

Constraining atmospheric composition from the outflow: helium observations reveal the fundamental properties of two planets straddling the radius gap

Kavli Affiliate: Avi Shporer | First 5 Authors: Michael Zhang, Jacob L. Bean, David Wilson, Girish Duvvuri, Christian Schneider | Summary: TOI-836 is a ~2-3 Gyr K dwarf with an inner super Earth ($R=1.7 R_oplus$, $P=3.8$ d) and an outer mini Neptune ($R=2.6 R_oplus$, $P=8.6$ d). JWST/NIRSpec 2.8–5.2 $mu$m transmission spectra are flat for both […]

Enhancing Direct Detection of Higgsino Dark Matter

Kavli Affiliate: Peter W. Graham | First 5 Authors: Peter W. Graham, Harikrishnan Ramani, Samuel S. Y. Wong, , | Summary: While much supersymmetric weakly interacting massive particle (WIMP) parameter space has been ruled out, one remaining important candidate is Higgsino dark matter. The Higgsino can naturally realize the "inelastic dark matter" scenario, where the […]

Witnessing the onset of reionisation via Lyman-$α$ emission at redshift 13

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Joris Witstok, Peter Jakobsen, Roberto Maiolino, Jakob M. Helton, Benjamin D. Johnson | Summary: $require{mediawiki-texvc}$Cosmic Reionisation commenced when ultraviolet (UV) radiation produced in the first galaxies began illuminating the cold, neutral gas that filled the primordial Universe. Recent James Webb Space Telescope (JWST) observations have shown that […]
