The Baryonic Faber-Jackson Relation and Fundamental Plane of Galaxy Groups, Elliptical Galaxies, and Dwarf Galaxies
Yong Tian, Federico Lelli, Marcel S. Pawlowski +7
The baryonic Faber-Jackson relation (BFJR) links the baryonic mass of pressure-supported systems to their mean velocity dispersion. For elliptical galaxies, the BFJR is thought to…
Hubble Astrometry for the Local Group and Beyond in the 2030s
S. Tony Sohn, Paul Bennet, Kevin Andrew McKinnon +23
Hubble's long, stable astrometric baseline creates a rare opportunity for discovery in the Local Group and beyond. Many nearby galaxies, streams, and star clusters already have arc…
Detectability of Satellite Planes in Mock Observations of Isolated L* Galaxies
Ethan Crosby, Marcel S. Pawlowski, Oliver Müller +1
The existence and prevalence of planar, co-rotating distributions of satellite galaxies around L* host galaxies in the local universe remains a subject of ongoing debate. Despite n…
The radial acceleration relation at the EDGE of galaxy formation: testing its universality in low-mass dwarf galaxies
Mariana P. Júlio, Justin I. Read, Marcel S. Pawlowski +6
A tight correlation between the baryonic and observed acceleration of galaxies has been reported over a wide range of mass () - the Radi…
Tracing satellite planes in the Sculptor group: II. Discovery of five faint dwarf galaxies in the DESI Legacy Survey
David Martinez-Delgado, Michael Stein, Marcel S. Pawlowski +5
Although substantial progress has been made in reconciling LCDM simulations with the observed abundance and distribution of satellite galaxies, important tensions persist. Studying…
HST Proper Motions of Andromeda V and VI
Dana I. Casetti-Dinescu, Marcel S. Pawlowski, Terrence M. Girard +3
We measure the absolute proper motions of Andromeda V (And V) and Andromeda VI/Pegasus (And VI) dwarf galaxies, satellites of M31 located near its galactic plane. And VI is located…
