Probing Cosmic Reionization and Molecular Gas Growth with TIME
Guochao Sun, Tzu-Ching Chang, Bade D. Uzgil +23
Line intensity mapping (LIM) provides a unique and powerful means to probe cosmic structures by measuring the aggregate line emission from all galaxies across redshift. The method…
Ubiquitous Molecular Outflows in z > 4 Massive, Dusty Galaxies II. Momentum-Driven Winds Powered by Star Formation in the Early Universe
Justin S. Spilker, Manuel Aravena, Kedar A. Phadke +13
Galactic outflows of molecular gas are a common occurrence in galaxies and may represent a mechanism by which galaxies self-regulate their growth, redistributing gas that could oth…
Ubiquitous Molecular Outflows in z > 4 Massive, Dusty Galaxies I. Sample Overview and Clumpy Structure in Molecular Outflows on 500pc Scales
Justin S. Spilker, Kedar A. Phadke, Manuel Aravena +14
Massive galaxy-scale outflows of gas are one of the most commonly-invoked mechanisms to regulate the growth and evolution of galaxies throughout the universe. While the gas in outf…
Betelgeuse scope: Single-mode-fibers-assisted optical interferometer design for dedicated stellar activity monitoring
Narsireddy Anugu, Katie M. Morzinski, Josh Eisner +12
Betelgeuse has gone through a sudden shift in its brightness and dimmed mysteriously. This is likely caused by a hot blob of plasma ejected from Betelgeuse and then cooled to obscu…
Overdensities of Submillimetre-Bright Sources around Candidate Protocluster Cores Selected from the South Pole Telescope Survey
George Wang, Ryley Hill, S. C. Chapman +19
We present APEX-LABOCA 870 micron observations of the fields surrounding the nine brightest, high-redshift, unlensed objects discovered in the South Pole Telescope's (SPT) 2500 squ…
Gravitational Test Beyond the First Post-Newtonian Order with the Shadow of the M87 Black Hole
Dimitrios Psaltis, Lia Medeiros, Pierre Christian +185
The 2017 Event Horizon Telescope (EHT) observations of the central source in M87 have led to the first measurement of the size of a black-hole shadow. This observation offers a new…
Biases and Cosmic Variance in Molecular Gas Abundance Measurements
Ryan P. Keenan, Daniel P. Marrone, Garrett K. Keating
Recent deep millimeter-wave surveys attempt to measure the carbon monoxide (CO) luminosity function and mean molecular gas density through blind detections of CO emission lines. Wh…
The Terahertz Intensity Mapper (TIM): a Next-Generation Experiment for Galaxy Evolution Studies
Joaquin Vieira, James Aguirre, C. Matt Bradford +22
Understanding the formation and evolution of galaxies over cosmic time is one of the foremost goals of astrophysics and cosmology today. The cosmic star formation rate has undergon…
Monitoring the Morphology of M87* in 2009-2017 with the Event Horizon Telescope
Maciek Wielgus, Kazunori Akiyama, Lindy Blackburn +26
The Event Horizon Telescope (EHT) has recently delivered the first resolved images of M87*, the supermassive black hole in the center of the M87 galaxy. These images were produced…
The Shape of the Black Hole Photon Ring: A Precise Test of Strong-Field General Relativity
Samuel E. Gralla, Alexandru Lupsasca, Daniel P. Marrone
We propose a new test of strong-field general relativity (GR) based on the universal interferometric signature of the black hole photon ring. The photon ring is a narrow ring-shape…
An Intensity Mapping Detection of Aggregate CO Line Emission at 3 mm
Garrett K. Keating, Daniel P. Marrone, Geoffrey C. Bower +1
We present a detection of molecular gas emission at using the technique of line intensity mapping. We make use of a pair of 3 mm interferometric data sets, the first fro…
Optical and near-infrared observations of the SPT2349-56 proto-cluster core at z = 4.3
K. M. Rotermund, S. C. Chapman, K. A. Phadke +20
We present Gemini-S and {\it Spitzer}-IRAC optical-through-near-IR observations in the field of the SPT2349-56 proto-cluster at . We detect optical/IR counterparts for only…
The Complete Redshift Distribution of Dusty Star-forming Galaxies from the SPT-SZ Survey
C. Reuter, J. D. Vieira, J. S. Spilker +21
The South Pole Telescope (SPT) has systematically identified 81 high-redshift, strongly gravitationally lensed, dusty star-forming galaxies (DSFGs) in a 2500 square degree cosmolog…
Markov Chains for Horizons (MARCH). I. Identifying Biases in Fitting Theoretical Models to Event Horizon Telescope Observations
Dimitrios Psaltis, Feryal Ozel, Lia Medeiros +7
We introduce a new Markov Chain Monte Carlo (MCMC) algorithm with parallel tempering for fitting theoretical models of horizon-scale images of black holes to the interferometric da…
SYMBA: An end-to-end VLBI synthetic data generation pipeline
F. Roelofs, M. Janssen, I. Natarajan +203
Realistic synthetic observations of theoretical source models are essential for our understanding of real observational data. In using synthetic data, one can verify the extent to…
Millimeter-wave Point Sources from the 2500-square-degree SPT-SZ Survey: Catalog and Population Statistics
W. B. Everett, L. Zhang, T. M. Crawford +45
We present a catalog of emissive point sources detected in the SPT-SZ survey, a contiguous 2530-square-degree area surveyed with the South Pole Telescope (SPT) from 2008 - 2011 in…
