Cross-correlations between the CLAMATO Lyman-alpha forest and galaxies within the COSMOS field

Posted by klaurent Tokyo

Kavli Affiliate: Khee-Gan Lee | Summary:We compute the 3D cross-correlation between the absorption of the $zsim 2.3$ Lyman-alpha forest measured by the COSMOS Lyman-Alpha Mapping And Tomography Observations (CLAMATO) survey, and 1642 foreground galaxies with spectroscopic redshifts from several different surveys, including 3D-HST, CLAMATO, zCOSMOS-Deep, MOSDEF, and VUDS. For each survey, we compare the measured […]

When (not) to trust Monte Carlo approximations for hierarchical Bayesian inference

Posted by klaurent MIT

Kavli Affiliate: Salvatore Vitale | Summary:The coming years of gravitational wave astrophysics promises thousands of new detections, which can unlock fundamental scientific insights if the information in each observation can be properly synthesized into a coherent picture. State-of-the-art approaches often accomplish this with hierarchical Bayesian inference. However, this typically relies on Monte Carlo approximations that […]

DART: A GUI Pipeline for Aligning Histological Brain Sections to 3D Atlases and Automating Laser Microdissection

Posted by dbos Hopkins

Kavli Affiliate: Justus M Kebschull | Authors: Rishi Koneru, Manjari M-G Anant, Hyopil Kim, Julian Cheron and Justus M Kebschull | Summary: The precise dissection of anatomically defined brain regions is the basis of many workflows in neurobiology. Traditionally, brain regions of interest are defined by visual inspection of tissue sections, followed by manual dissection. […]

Constraining Gas Mass Fractions in Galaxy Groups and Clusters with the First CHIME/FRB Outrigger

Posted by klaurent MIT

Kavli Affiliate: Kiyoshi Masui | Summary:In recent years, localized fast radio bursts (FRBs) have emerged as a powerful tool to study the structure of the baryonic matter in the universe. Their dispersion measures (DMs) scale linearly with electron density independent of gas temperature, making them particularly well suited to studying the intragroup medium (IGrM), where […]

Carnegie Supernova Project: Fast-Declining Type Ia Supernovae as Cosmological Distance Indicators

Posted by klaurent Chicago

Kavli Affiliate: Wendy Freedman | Summary:In this paper, the suitability of fast-declining Type Ia supernovae (SNe Ia) as cosmological standard candles is examined utilizing a Hubble Flow sample of 43 of these objects observed by the Carnegie Supernova Project (CSP). We confirm previous suggestions that fast-declining SNe Ia offer a viable method for estimating distances […]
