Kavli Affiliate: Sarah Woolley | Authors: Erin M Wall, Nicholas Vidas-Guscic, Jasmien Orije, Elisabeth Jonckers, Marleen Verhoye, Annemie Van der Linden and Sarah Cushing Woolley | Summary: Social relationships profoundly shape the perception of communication signals. In animals that form long-term social bonds, sensory cues such as vocalizations, scent, or physical appearance, and rewarding mating […]
Kavli Affiliate: Gregory Herczeg | Summary:We present two-epoch JWST NIRSpec and MIRI observations of the young protostar EC 53 (V371 Ser), a periodically variable source with well-characterized quiescent and burst phases. The spectra in both epochs show absorption in the CO overtone ($sim$2.3 $μ$m) and fundamental ($sim$4.6 $μ$m) bands and the H$_2$O stretching ($sim$2.7 $μ$m) […]
Kavli Affiliate: Roberto Maiolino | Summary:The Centaurus cluster is one of the most important archetypes of radio-mode AGN feedback, with its central galaxy, NGC 4696, launching powerful jets that inflate X-ray cavities and regulate cooling and star formation. NGC 4696 lies within a spectacular multiphase nebula of filaments extending over tens of kiloparsecs and spanning […]
Kavli Affiliate: George Efstathiou | Summary:We investigate the impact of mixed cold and fuzzy dark matter (MDM) cosmologies on the halo mass function (HMF) using numerical simulations performed with the AxiREPO framework. We consider models in which an ultralight axion-like component with mass $m =10^-24.5 mathrmeV$ constitutes a fraction $f leq 0.3$ of the total […]
Kavli Affiliate: Blake Sherwin | Summary:Ultralight axions (ULAs) are well-motivated dark matter particle candidates that arise in many extensions of the Standard Model of particle physics. ULAs with mass $m_mathrma lesssim 10^-27$ eV have been strongly constrained by cosmic microwave background (CMB) observations in temperature and polarization. We fit recent measurements of gravitational lensing of […]
Kavli Affiliate: Lijing Shao | Summary:We construct analytic solutions to the bumblebee gravity theory in static and spherically symmetric spacetimes, where the bumblebee vector field admits only a non-vanishing temporal component. In particular, we identify the parameter space that allows for asymptotically flat black hole solutions. We further investigate the thermodynamic properties of these black […]

Huganir, Austin R Graves, Adam S Charles and Michael I Miller | Summary: Synapses are the fundamental unit of neural connectivity, exhibiting dynamic functional and structural changes that enable the brain to learn, adapt, […]
Kavli Affiliate: Michael Turner | Summary:Measurements of baryon acoustic oscillations (BAO) by the Dark Energy Spectroscopic Instrument (DESI) have revealed evidence for dark energy that evolves. If local distance measurements are analyzed with the $w_0w_a$ models preferred by the DESI measurements, the value for the Hubble constant can be as much as $2.5,mathrmkm,s^-1Mpc^-1$ smaller than […]
Kavli Affiliate: Kiyoshi Masui | Summary:Jointly analyzing the sightlines of arcsecond-localized fast radio bursts (FRBs) and UV-bright quasars (QSOs) nearby in projection has the potential to provide strong constraints on the phases, mass distributions, and magnetic structure of the diffuse universe. Each probe supplies what the other cannot: FRBs provide integrated electron columns (DM), line-of-sight […]
