Origins Space Telescope Mission Concept Study Report
M. Meixner, A. Cooray, D. Leisawitz +66
The Origins Space Telescope (Origins) traces our cosmic history, from the formation of the first galaxies and the rise of metals to the development of habitable worlds and present-…
Modeling Dust and Starlight in Galaxies Observed by Spitzer and Herschel: The KINGFISH Sample
G. Aniano, B. T. Draine, L. K. Hunt +30
Dust and starlight are modeled for the KINGFISH project galaxies. With data from 3.6 micron to 500 micron, models are strongly constrained. For each pixel in each galaxy we estimat…
How to Fuel an AGN: Mapping Circumnuclear Gas in NGC 6240 with ALMA
Anne M. Medling, George C. Privon, Loreto Barcos-Muñoz +15
Dynamical black hole mass measurements in some gas-rich galaxy mergers indicate that they are overmassive relative to their host galaxy properties. Overmassive black holes in these…
The Potential of Exozodiacal Disks Observations with the WFIRST Coronagraph Instrument
B. Mennesson, V. Bailey, J. Kasdin +60
The Wide Field Infrared Survey Telescope (WFIRST) Coronagraph Instrument (CGI) will be the first high-performance stellar coronagraph using active wavefront control for deep starli…
ATLAS Probe: Breakthrough Science of Galaxy Evolution, Cosmology, Milky Way, and the Solar System
Yun Wang, Mark Dickinson, Lynne Hillenbrand +45
ATLAS (Astrophysics Telescope for Large Area Spectroscopy) is a concept for a NASA probe-class space mission. It is the spectroscopic follow-up mission to WFIRST, boosting its scie…
Molecular gas and dust properties of galaxies from the Great Observatories All-sky LIRG Survey
R. Herrero-Illana, G. C. Privon, A. S. Evans +23
We present IRAM-30m Telescope CO and CO observations of a sample of 55 luminous and ultraluminous infrared galaxies (LIRGs and ULIRGs) in the local universe. This sam…
A Very Large Array Survey of Luminous Extranuclear Star-forming Regions in Luminous Infrared Galaxies in GOALS
S. T. Linden, Y. Song, A. S. Evans +13
We present the first results of a high-resolution Karl G. Jansky Very Large Array (VLA) imaging survey of luminous and ultra-luminous infrared galaxies (U/LIRGs) in the Great Obser…
The Life Cycle of Dust
Sarah Sadavoy, Mikako Matsuura, Lee Armus +24
Dust offers a unique probe of the interstellar medium (ISM) across multiple size, density, and temperature scales. Dust is detected in outflows of evolved stars, star-forming molec…
Astro2020 White Paper: On the Origin of the Initial Mass Function
Roberta Paladini, Matthew Povich, Lee Armus +10
It is usually assumed that the stellar initial mass function (IMF) takes a universal form and that there exists a direct mapping between this and the distribution of natal core mas…
Astro2020 Science White Paper: Cold Gas Outflows, Feedback, and the Shaping of Galaxies
Alberto D. Bolatto, Lee Armus, Sylvain Veilleux +12
There is wide consensus that galaxy outflows are one of the most important processes determining the evolution of galaxies through cosmic time, for example playing a key role in sh…
Warm H as a probe of massive accretion and feedback through shocks and turbulence across cosmic time
Philip Appleton, Lee Armus, Francois Boulanger +22
Galaxy formation depends on a complex interplay between gravitational collapse, gas accretion, merging, and feedback processes. Yet, after many decades of investigation, these conc…
Taking Census of Massive, Star-Forming Galaxies formed <1 Gyr After the Big Bang
Caitlin M. Casey, Peter Capak, Johannes Staguhn +24
Two decades of effort have been poured into both single-dish and interferometric millimeter-wave surveys of the sky to infer the volume density of dusty star-forming galaxies (DSFG…
Simultaneous Measurements of Star Formation and Supermassive Black Hole Growth in Galaxies
Alexandra Pope, Lee Armus, Eric Murphy +29
Galaxies grow their supermassive black holes in concert with their stars, although the relationship between these major galactic components is poorly understood. Observations of th…
Cosmic Dawn and Reionization: Astrophysics in the Final Frontier
Asantha Cooray, James Aguirre, Yacine Ali-Haimoud +71
The cosmic dawn and epoch of reionization mark the time period in the universe when stars, galaxies, and blackhole seeds first formed and the intergalactic medium changed from neut…
Origins Space Telescope: predictions for far-IR spectroscopic surveys
Matteo Bonato, Gianfranco De Zotti, David Leisawitz +9
We illustrate the extraordinary potential of the (far-IR) Origins Survey Spectrometer (OSS) on board the Origins Space Telescope (OST) to address a variety of open issues on the co…
The Wide Field Infrared Survey Telescope: 100 Hubbles for the 2020s
Rachel Akeson, Lee Armus, Etienne Bachelet +103
The Wide Field Infrared Survey Telescope (WFIRST) is a 2.4m space telescope with a 0.281 deg^2 field of view for near-IR imaging and slitless spectroscopy and a coronagraph designe…
Key Technologies for the Wide Field Infrared Survey Telescope Coronagraph Instrument
Vanessa P. Bailey, Lee Armus, Bala Balasubramanian +84
The Wide Field Infrared Survey Telescope (WFIRST) Coronagraph Instrument (CGI) is a high-contrast imager and integral field spectrograph that will enable the study of exoplanets an…
