Scylla VI: Parsec-Scale Dust Extinction Maps in the SMC and LMC

Christina W. Lindberg, Claire E. Murray, Christopher J. R. Clark +14

We present a novel methodology for mapping dust extinction in nearby galaxies at parsec-scale resolution. We apply it to HST 68 fields within the Small and Large Magellanic Clouds…

A Deep, High-Angular Resolution 3D Dust Map of the Southern Galactic Plane

Catherine Zucker, Andrew K. Saydjari, Joshua S. Speagle +8

We present a deep, high-angular resolution 3D dust map of the southern Galactic plane over and built on photometry from the DECaPS2 su…

ChronoFlow: A Data-Driven Model for Gyrochronology

Phil R. Van-Lane, Joshua S. Speagle, Gwendolyn M. Eadie +6

Gyrochronology is a technique for constraining stellar ages using rotation periods, which change over a star's main sequence lifetime due to magnetic braking. This technique shows…

Origin of the IRAS Vela Shell: New Insights from 3D Dust Mapping

Bore Annie Gao, Catherine Zucker, Tirupati Kumara Sridharan +15

The IRAS Vela Shell (IVS) is a structure of enhanced FIR emission located towards the Gum Nebula, a prominent region of emission in the local Milky Way shaped by various…

The H sky in three dimensions

Lewis McCallum, Kenneth Wood, Robert Benjamin +4

We combine parallax distances to nearby O stars with parsec-scale resolution three-dimensional dust maps of the local region of the Milky Way (within 1.25 kpc of the Sun) to simula…

Deriving Stellar Properties, Distances, and Reddenings using Photometry and Astrometry with BRUTUS

Joshua S. Speagle, Catherine Zucker, Angus Beane +18

We present brutus, an open source Python package for quickly deriving stellar properties, distances, and reddenings to stars based on grids of stellar models constrained by photome…
