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…
Recovering the gravitational potential in a rotating frame: Deep Potential applied to a simulated barred galaxy
Taavet Kalda, Gregory M. Green, Soumavo Ghosh
Stellar kinematics provide a window into the gravitational field, and therefore into the distribution of all mass, including dark matter. Deep Potential is a method for determining…
Roman Early-Definition Astrophysics Survey Opportunity: Galactic Roman Infrared Plane Survey (GRIPS)
Roberta Paladini, Catherine Zucker, Robert Benjamin +67
A wide-field near-infrared survey of the Galactic disk and bulge/bar(s) is supported by a large representation of the community of Galactic astronomers. The combination of sensitiv…
Quantifying the influence of bars on action-based dynamical modelling of disc galaxies
Soumavo Ghosh, Wilma H. Trick, Gregory M. Green
Action-based dynamical modelling, using stars as dynamical tracers, is an excellent diagnostic to estimate the underlying axisymmetric matter distribution of the Milky Way. However…
The First 3 3D Map of ISM Dust Temperature
Ioana A. Zelko, Douglas P. Finkbeiner, Albert Lee +1
We present the first large-scale 3D map of interstellar dust temperature. We build upon existing 3D reddening maps derived from starlight absorption (Bayestar19), covering 3/4 of t…
An empirical model of the Gaia DR3 selection function
Tristan Cantat-Gaudin, Morgan Fouesneau, Hans-Walter Rix +11
Interpreting and modelling astronomical catalogues requires an understanding of the catalogues' completeness or selection function: objects of what properties had a chance to end u…
The Dark Energy Camera Plane Survey 2 (DECaPS2): More Sky, Less Bias, and Better Uncertainties
A. K. Saydjari, E. F. Schlafly, D. Lang +10
Deep optical and near-infrared imaging of the entire Galactic plane is essential for understanding our Galaxy's stars, gas, and dust. The second data release of the DECam Plane Sur…
Deep Potential: Recovering the gravitational potential from a snapshot of phase space
Gregory M. Green, Yuan-Sen Ting, Harshil Kamdar
One of the major goals of the field of Milky Way dynamics is to recover the gravitational potential field. Mapping the potential would allow us to determine the spatial distributio…
Science with the Ultraviolet Explorer (UVEX)
S. R. Kulkarni, Fiona A. Harrison, Brian W. Grefenstette +53
UVEX is a proposed medium class Explorer mission designed to provide crucial missing capabilities that will address objectives central to a broad range of modern astrophysics. The…
Deep Potential: Recovering the gravitational potential from a snapshot of phase space
Gregory M. Green, Yuan-Sen Ting
One of the major goals of the field of Milky Way dynamics is to recover the gravitational potential field. Mapping the potential would allow us to determine the spatial distributio…
Constraining the Distance to the North Polar Spur with Gaia DR2
Kaustav K. Das, Catherine Zucker, Joshua S. Speagle +3
The North Polar Spur (NPS) is one of the largest structures observed in the Milky Way in both the radio and soft x-rays. While several predictions have been made regarding the orig…
Data-Driven Stellar Models
Gregory M. Green, Hans-Walter Rix, Leon Tschesche +7
We develop a data-driven model to map stellar parameters (effective temperature, surface gravity and metallicity) accurately and precisely to broad-band stellar photometry. This mo…
A Galactic-scale gas wave in the Solar Neighborhood
João Alves, Catherine Zucker, Alyssa A. Goodman +6
For the past 150 years, the prevailing view of the local Interstellar Medium (ISM) was based on a peculiarity known as the Gould's Belt, an expanding ring of young stars, gas, and…
A Compendium of Distances to Molecular Clouds in the Star Formation Handbook
Catherine Zucker, Joshua S. Speagle, Edward F. Schlafly +4
Accurate distances to local molecular clouds are critical for understanding the star and planet formation process, yet distance measurements are often obtained inhomogeneously on a…
Milky Way Satellite Census. II. Galaxy--Halo Connection Constraints Including the Impact of the Large Magellanic Cloud
E. O. Nadler, R. H. Wechsler, K. Bechtol +63
The population of Milky Way (MW) satellites contains the faintest known galaxies and thus provides essential insight into galaxy formation and dark matter microphysics. Here we com…
A 3D Dust Map Based on Gaia, Pan-STARRS 1 and 2MASS
Gregory M. Green, Edward F. Schlafly, Catherine Zucker +2
We present a new three-dimensional map of dust reddening, based on Gaia parallaxes and stellar photometry from Pan-STARRS 1 and 2MASS. This map covers the sky north of a declinatio…
