Kavli Affiliate: Seth Blackshaw | Authors: Leah J Elias, Harrison Khoo, Francois Kroll, Caroline Zhang, Soojung C Hur, Jason Rihel and Seth Blackshaw | Summary: While sleep deprivation broadly disrupts health and well-being, the neural and molecular mechanisms that signal increased sleep pressure remain poorly understood. A key obstacle to progress is the fact that […]
Kavli Affiliate: Edvard Moser and May-Britt Moser | Authors: Christine M Lykken, Benjamin R Kanter, Anne Nagelhus, Jordan Carpenter, Matteo Guardamagna, Edvard I Moser and May-Britt Moser | Summary: A systems-level understanding of cortical computation requires insight into how neural codes are transformed across distinct brain circuits. In the mammalian cortex, one of the few […]
Kavli Affiliate: Alex Pollen | Authors: Jingwen W Ding, Chang N Kim, Megan S Ostrowski, Yashodara Abeykoon, Bryan J Pavlovic, Jenelle L Wallace, Tomasz J Nowakowski and Alex A Pollen | Summary: Human cortical neurogenesis involves conserved and specialized developmental processes during a restricted window of prenatal development. Radial glia (RG) neural stem cells shape […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: John D. Silverman, John D. Silverman, , , | Summary: Contamination-free assessments of the interstellar medium and star formation in quasar host galaxies, particularly based on the far-infrared, offer insights into the role of supermassive black holes in galaxy evolution. Motivated by predictions of quasar heating […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Chun-Hao To, Chun-Hao To, , , | Summary: We present the first detection of weak gravitational lensing around spectroscopically confirmed dwarf galaxies, using the large overlap between DESI DR1 spectroscopic data and DECADE/DES weak lensing catalogs. A clean dwarf galaxy sample with well-defined redshift and stellar […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Gareth C. Jones, Gareth C. Jones, , , | Summary: Recent photometric surveys with JWST have revealed a significant population of mysterious objects with red colours, compact morphologies, frequent signs of active galactic nucleus (AGN) activity, and negligible X-ray emission. These ‘Little Red Dots’ (LRDs) have been […]
Kavli Affiliate: Lile Wang | First 5 Authors: Shunyuan Mao, Shunyuan Mao, , , | Summary: Accretion disks are ubiquitous in astrophysics, appearing in diverse environments from planet-forming systems to X-ray binaries and active galactic nuclei. Traditionally, modeling their dynamics requires computationally intensive (magneto)hydrodynamic simulations. Recently, Physics-Informed Neural Networks (PINNs) have emerged as a promising […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Erin Kado-Fong, Erin Kado-Fong, , , | Summary: Recent efforts have extended our view of the number and properties of satellite galaxies beyond the Local Group firmly down to $rm M_starsim 10^6 M_odot$. A similarly complete view of the field dwarf population has lagged behind. Using […]

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Helena Treiber, Helena Treiber, , , | Summary: We present the most precise and lowest-mass weak lensing measurements of dwarf galaxies to date, enabled by spectroscopic lenses from the Dark Energy Spectroscopic Instrument (DESI) and photometric lenses from the Dark Energy Survey (DES) calibrated with DESI […]
