A Comparison of Star-Forming Clumps and Tidal Tails in Local Mergers and High Redshift Galaxies
Debra Meloy Elmegreen, Bruce G. Elmegreen, Bradley C. Whitmore +8
The Clusters, Clumps, Dust, and Gas in Extreme Star-Forming Galaxies (CCDG) survey with the Hubble Space Telescope includes multi-wavelength imaging of 13 galaxies less than 100 Mp…
Physics-Informed Neural Network Super Resolution for Advection-Diffusion Models
Chulin Wang, Eloisa Bentivegna, Wang Zhou +2
Physics-informed neural networks (NN) are an emerging technique to improve spatial resolution and enforce physical consistency of data from physics models or satellite observations…
Relationships between the Stellar, Gaseous, and Star Formation Disks in LITTLE THINGS Dwarf Irregular Galaxies: Indirect Evidence for Substantial Fractions of Dark Molecular Gas
Deidre A. Hunter, Bruce G. Elmegreen, Esther Goldberger +7
The stellar, gaseous and young stellar disks in the LITTLE THINGS sample of nearby dIrrs are fitted with functions to search for correlations between the parameters. We find that t…
Stellar scattering and the formation of exponential discs in self-gravitating systems
Jian Wu, Curtis Struck, Elena D'Onghia +1
We show, using the N-body code GADGET-2, that stellar scattering by massive clumps can produce exponential discs, and the effectiveness of the process depends on the mass of scatte…
AstroSat detection of Lyman continuum emission from a z=1.42 galaxy
Kanak Saha, Shyam N. Tandon, Charlotte Simmonds +10
One of the outstanding problems of current observational cosmology is to understand the nature of sources that produced the bulk of the ionizing radiation after the Cosmic Dark Age…
Structure and rotation of young massive star clusters in a simulated dwarf starburst
Natalia Lahén, Thorsten Naab, Peter H. Johansson +3
We analyze the three-dimensional shapes and kinematics of the young star cluster population forming in a high-resolution GRIFFIN project simulation of a metal-poor dwarf galaxy sta…
