Characterization of ultrathin nickel films deposited by thermal laser evaporation

Kavli Affiliate: Austin Minnich | Summary:Thermal laser evaporation is a physical vapor deposition technique of increasing interest because of its ability to evaporate essentially any solid element, even the most refractory such as W. However, many films deposited by this method, especially non-epitaxial films, remain to be characterized; further, key system components such as the […]

Dust in the Average Galaxy: Attenuation, Emission, and Opacity from 0

Kavli Affiliate: Kohei Inayoshi | Summary:We present constraints on the dust emission and attenuation properties of galaxies across 0<z<7 using JWST imaging from the COSMOS-Web Survey combined with deep FIR/(sub)millimeter data from Spitzer, Herschel, SCUBA-2, NIKA-2 and ALMA. We analyze over 500,000 galaxies to independently constrain attenuation in the rest-frame UV/optical as well as dust […]

Continuous partitioning of neuronal variability

Kavli Affiliate: Adam S. Charles | Authors: Anuththara Rupasinghe, Adam S Charles and Jonathan W Pillow | Summary: Neurons exhibit substantial trial-to-trial variability in response to repeated stimuli, posing a major challenge for understanding the information content of neural spike trains. In the visual cortex, responses show greater-than-Poisson variability, whose origins and structure remain unclear. […]

Hawai`i Supernova Flows: Bulk Flow Measurements using SNe Ia in the Optical and NIR

Kavli Affiliate: Kaisey Mandel | Summary:The present day peculiar velocity-field was sourced by primordial density fluctuations and sculpted over the lifespan of the Universe. Cosmological models such as $Λ$CDM make predictions for various statistical properties of peculiar velocities. Bulk flow, the average velocity within a given volume, has an expectation value of $vec0$ due to […]

Chemical enrichment of the Perseus cluster core seen by XRISM/Resolve

Kavli Affiliate: Erin Kara | Summary:The intracluster medium (ICM) is rich in chemical elements, produced by core-collapse (SNcc) and Type Ia supernovae (SNIa) over the last $sim$12 Gyr. Whereas cluster outskirts are uniformly enriched with Fe at $sim$0.3 solar – strongly suggesting that the gas had been pre-enriched during or before the assembly of galaxies […]

Constraints on Late-Time Flaring from Luminous Fast Blue Optical Transients using the Transiting Exoplanet Survey Satellite and the Zwicky Transient Facility

Kavli Affiliate: Michael Fausnaugh | Summary:The Luminous Fast Blue Optical Transient (LFBOT) AT2022tsd exhibited minutes-timescale optical flares in the tens of days following the initial transient event, likely due to a central engine — either an accreting black hole or a magnetar. In this paper, we use data from the Transiting Exoplanet Survey Satellite (TESS) […]

Dynamically suppressed lattice rotations in SrTiO$_3$ as a basis for photo-induced ferroelectricity

Kavli Affiliate: Ankit Disa | Summary:Photo-induced ferroelectricity in the quantum paraelectric SrTiO$_3$ involves the dynamical interplay between a coherently driven Ti-O stretching vibration and multiple structural degrees of freedom, including antiferrodistortive rotations, strain, and the polar mode instability. In the high-temperature cubic phase, in the absence of average antiferrodistortion, time-resolved X-ray diffuse scattering has evidenced […]

The Dynamics of Old Inner Galaxy Stars in Milky Way-mass Galaxies Using FIRE-2 Simulations

Kavli Affiliate: Lina Necib | Summary:Understanding how galaxies like the Milky Way assembled over cosmic time remains a central question in astrophysics. Understanding the processes that shaped their formation and evolution is greatly enhanced by the joint use of observational data and high-resolution cosmological simulations. Old stars in the inner regions of galaxies serve as […]
