Initial Mass Function Variability (or not) Among \\ Low-Velocity Dispersion, Compact Stellar Systems
Alexa Villaume, Jean Brodie, Charlie Conroy +2
Analyses of strong gravitational lenses, galaxy-scale kinematics, and absorption line stellar population synthesis (SPS) have all concluded that the stellar initial mass function (…
The Survey of Water and Ammonia in the Galactic Center (SWAG): Molecular Cloud Evolution in the Central Molecular Zone
Nico Krieger, Jürgen Ott, Henrik Beuther +21
The Survey of Water and Ammonia in the Galactic Center (SWAG) covers the Central Molecular Zone (CMZ) of the Milky Way at frequencies between 21.2 and 25.4 GHz obtained at the Aust…
Deep Subaru Hyper Suprime-Cam observations of Milky Way satellites Columba I and Triangulum II
Jeffrey L. Carlin, David J. Sand, Ricardo R. Munoz +9
We present deep, wide-field Subaru Hyper Suprime-Cam photometry of two recently discovered satellites of the Milky Way (MW): Columba I and Triangulum II. The color magnitude diagra…
On the formation mechanisms of compact elliptical galaxies
Anna Ferre-Mateu, Duncan A. Forbes, Aaron J. Romanowsky +2
In order to investigate the formation mechanisms of the rare compact elliptical galaxies (cE) we have compiled a sample of 25 cEs with good SDSS spectra, covering a range of stella…
Unsupervised machine learning account of magnetic transitions in the Hubbard model
Kelvin Ch'ng, Nick Vazquez, Ehsan Khatami
We employ several unsupervised machine learning techniques, including autoencoders, random trees embedding, and t-distributed stochastic neighboring ensemble (t-SNE), to reduce the…
Extensive Globular Cluster Systems Associated with Ultra Diffuse Galaxies in the Coma Cluster
Pieter van Dokkum, Roberto Abraham, Aaron J. Romanowsky +7
We present Hubble Space Telescope imaging of two ultra diffuse galaxies (UDGs) with measured stellar velocity dispersions in the Coma cluster. The galaxies, Dragonfly 44 and DFX1,…
