Predicted Trends in Milky Way Bulge Proper Motion Rotation Curves: future Prospects for HST and LSST
Steven Gough-Kelly, Victor P. Debattista, William I. Clarkson +5
We use an -body+smoothed particle hydrodynamics simulation of an isolated barred galaxy to study the age dependence of bulge longitudinal proper motion () rotation curves.…
Stars in the Local Galactic Thick Disk and Halo in Gaia EDR3: A catalogue of Half a Million Local Main-sequence Stars with Photometric Metallicities
Bokyoung Kim, Sebastien Lépine
We present a catalogue of 551,214 main-sequence stars in the local ( kpc) Galactic thick disk and halo, based on a search of stars with large proper motions ($μ_{\mathrm{tot…
The Incidence of X-ray selected AGN in Nearby Galaxies
Keir L. Birchall, M. G. Watson, J. Aird +1
We present the identification and analysis of an unbiased sample of AGN that lie within the local galaxy population. Using the MPA-JHU catalogue (based on SDSS DR8) and 3XMM DR7 we…
Identifying RR Lyrae in the ZTF DR3 dataset
Kuan-Wei Huang, Sergey E. Koposov
We present a RR Lyrae (RRL) catalogue based on the combination of the third data release of the Zwicky Transient Facility (ZTF DR3) and \textit{Gaia} EDR3. We use a multi-step clas…
Multi-Epoch Machine Learning 1: Unravelling Nature vs Nurture for Galaxy Formation
Robert McGibbon, Sadegh Khochfar
We present a novel machine learning method for predicting the baryonic properties of dark matter only subhalos from N-body simulations. Our model is built using the extremely rando…
HI observations of the MATLAS dwarf and ultra-diffuse galaxies
Melina Poulain, Francine R. Marleau, Rebecca Habas +8
The presence of HI gas in galaxies is inextricably linked to their morphology and evolution. This paper aims to understand the HI content of the already identified 2210 dwarfs loca…
