Cosmological Constraints from Full-Scale Clustering and Galaxy-Galaxy Lensing with DESI DR1

Posted by klaurent Stanford

Kavli Affiliate: Risa Wechsler | Summary:We present constraints on cosmic structure growth from the analysis of galaxy clustering and galaxy-galaxy lensing with galaxies from the Dark Energy Spectroscopic Instrument (DESI) Data Release 1. We analyze four samples drawn from the Bright Galaxy Survey (BGS) and the Luminous Red Galaxy (LRG) target classes. Projected galaxy clustering […]

The AIDA-TNG project. Abundance, radial distribution, and clustering properties of halos in alternative dark matter models

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | Summary:Warm and self-interactive dark matter cosmologies have been proposed as nonbaryonic solutions to the tensions between the $Λ$ cold dark matter model and observations at the kiloparsec scale. In this paper, we used the dark matter-only runs of the textscaida-tng project, a set of cosmological simulations of different sizes and […]

The AIDA-TNG project: dark matter profiles and concentrations in alternative dark matter models

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | Summary:In the standard Cold Dark Matter (CDM) scenario, the density profiles of dark matter haloes are well described by analytical models linking their concentration to halo mass. Alternative scenarios, such as warm dark matter (WDM) and self-interacting dark matter (SIDM), modify the inner structure of haloes and predict different profile […]

The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes

Posted by klaurent Stanford

Kavli Affiliate: Susan Clark | Summary:We present updated forecasts for the scientific performance of the degree-scale (0.5 deg FWHM at 93 GHz), deep-field survey to be conducted by the Simons Observatory (SO). By 2027, the SO Small Aperture Telescope (SAT) complement will be doubled from three to six telescopes, including a doubling of the detector […]

A Characterization of JWST MIRI Detector Persistence and Implications for High-Contrast Imaging

Posted by klaurent MIT

Kavli Affiliate: Andrew Vanderburg | Summary:The JWST MIRI detector exhibits a flux deficit persistence, but its timescales and impacts remain largely uncharacterized, particularly at the longest imaging wavelengths. In this study, we analyze full-field MIRI imager observations at 21 $μ$m (F2100W) to quantify detector persistence following a saturation event by a bright (K = 5.65 […]

XRISM view of a stellar flare: High-resolution Fe K spectra of HR 1099, an RS CVn-type star

Posted by klaurent MIT

Kavli Affiliate: Eric Miller | Summary:A high-resolution X-ray spectroscopic observation was made of the RS CVn-type binary star HR 1099 using the Resolve instrument onboard XRISM for its calibration purposes. During the $sim$400 ks telescope time covering 1.5 binary orbit, a flare lasting for $sim$100 ks was observed with a released X-ray radiation energy of […]
