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

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 Baryon Fractions in Galaxy Groups and Clusters with the First CHIME/FRB Outrigger

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Adam E. Lanman, Adam E. Lanman, , , | Summary: Fast radio bursts (FRBs) provide a sensitive probe of diffuse baryons: their dispersion measures (DMs) measure electron density independent of temperature and scale linearly with gas density. This makes them particularly well suited to studying the […]

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

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: M. M. Phillips, M. M. Phillips, , , | 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 […]

What’s the Buzz About GX 13+1? Constraining Coronal Geometry with QUEEN-BEE: A Bayesian Nested Sampling Framework for X-ray Polarization Rotation Analysis

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Swati Ravi, Swati Ravi, , , | Summary: Observations from the Imaging X-ray Polarimetry Explorer (IXPE) have revealed electric vector position angle (EVPA) rotation in several neutron star low-mass X-ray binaries, including the galactic X-ray burster GX 13+1. We developed a novel Bayesian nested sampling framework-"Q-U […]

Machine Learning Assisted Parameter-Space Searches for Lensed Gravitational Waves

Kavli Affiliate: Wayne Hu | First 5 Authors: Giulia Campailla, Giulia Campailla, , , | Summary: When a gravitational wave encounters a massive object along the line of sight, repeated copies of the original signal may be produced due to gravitational lensing. In this paper, we develop a series of new machine-learning based statistical methods […]
