Mantis Shrimp: Exploring Photometric Band Utilization in Computer Vision Networks for Photometric Redshift Estimation
Andrew Engel, Nell Byler, Adam Tsou +3
We present Mantis Shrimp, a multi-survey deep learning model for photometric redshift estimation that fuses ultra-violet (GALEX), optical (PanSTARRS), and infrared (UnWISE) imagery…
Preliminary Report on Mantis Shrimp: a Multi-Survey Computer Vision Photometric Redshift Model
Andrew Engel, Gautham Narayan, Nell Byler
The availability of large, public, multi-modal astronomical datasets presents an opportunity to execute novel research that straddles the line between science of AI and science of…
The BPT Diagram in Cosmological Galaxy Formation Simulations: Understanding the Physics Driving Offsets at High-Redshift
Prerak Garg, Desika Narayanan, Nell Byler +9
The Baldwin, Philips, & Terlevich diagram of [O III]/H vs. [N II]/H (hereafter N2-BPT) has long been used as a tool for classifying galaxies based on the dominant source of i…
A comparison of UV and optical metallicities in star-forming galaxies
Nell Byler, Lisa J Kewley, Jane R Rigby +5
Our ability to study the properties of the interstellar medium (ISM) in the earliest galaxies will rely on emission line diagnostics at rest-frame ultraviolet (UV) wavelengths. In…
Stellar Feedback and Resolved Stellar IFU Spectroscopy in the nearby Spiral Galaxy NGC 300
Anna F. McLeod, J. M. Diederik Kruijssen, Daniel R. Weisz +7
We present MUSE Integral Field Unit (IFU) observations of five individual HII regions in two giant (>100 pc in radius) star-forming complexes in the low-metallicity (~0.33 $Z_{\…
Comparison of Theoretical Starburst Photoionisation Models for Optical Diagnostics
Joshua J. D'Agostino, Lisa J. Kewley, Brent Groves +5
We study and compare different examples of stellar evolutionary synthesis input parameters used to produce photoionisation model grids using the MAPPINGS V modelling code. The aim…
Self-consistent predictions for LIER-like emission lines from post-AGB stars
Nell Byler, Julianne J. Dalcanton, Charlie Conroy +4
Early type galaxies (ETGs) frequently show emission from warm ionized gas. These Low Ionization Emission Regions (LIERs) were originally attributed to a central, low-luminosity act…
Astro2020 Science White Paper: Spatially Resolved UV Nebular Diagnostics in Star-Forming Galaxies
Bethan James, Danielle Berg, Rongmon Bordoloi +16
Diagnosing the physical and chemical conditions within star-forming galaxies (SFGs) is of paramount importance to understanding key components of galaxy formation and evolution: st…
The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library
D. S. Aguado, Romina Ahumada, Andres Almeida +230
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years o…
Physical Properties of II Zw 40's Super Star Cluster and Nebula: New Insights and Puzzles from UV Spectroscopy
Claus Leitherer, Nell Byler, Janice C. Lee +1
We analyze far-ultraviolet spectra and ancillary data of the super star cluster SSC-N and its surrounding H II region in the nearby dwarf galaxy II Zw 40. From the ultraviolet spec…
Stellar and nebular diagnostics in the UV for star-forming galaxies
Nell Byler, Julianne Dalcanton, Charlie Conroy +4
There is a long history of using optical emission and absorption lines to constrain the metallicity and ionization parameters of gas in galaxies. However, comparable diagnostics ar…
The Evolution and Properties of Rotating Massive Star Populations
Jieun Choi, Charlie Conroy, Nell Byler
We investigate the integrated properties of massive (>10 Msun), rotating, single-star stellar populations for a variety of initial rotation rates (v/vcrit=0.0, 0.2, 0.4, 0.5, and 0…
Nebular Continuum and Line Emission in Stellar Population Synthesis Models
Nell Byler, Julianne J. Dalcanton, Charlie Conroy +1
Accounting for nebular emission when modeling galaxy spectral energy distributions (SEDs) is important, as both line and continuum emission can contribute significantly to the tota…
Deriving Physical Properties from Broadband Photometry with Prospector: Description of the Model and a Demonstration of its Accuracy Using 129 Galaxies in the Local Universe
Joel Leja, Benjamin D. Johnson, Charlie Conroy +2
Broadband photometry of galaxies measures an unresolved mix of complex stellar populations, gas, and dust. Interpreting these data is a challenge for models: many studies have show…
Overview of the SDSS-IV MaNGA Survey: Mapping Nearby Galaxies at Apache Point Observatory
Kevin Bundy, Matthew A. Bershady, David R. Law +65
We present an overview of a new integral field spectroscopic survey called MaNGA (Mapping Nearby Galaxies at Apache Point Observatory), one of three core programs in the fourth-gen…
The Panchromatic Hubble Andromeda Treasury X. Ultraviolet to Infrared Photometry of 117 Million Equidistant Stars
