Design of SPT-SLIM focal plane; a spectroscopic imaging array for the South Pole Telescope
P. S. Barry, A. Anderson, B. Benson +15
The Summertime Line Intensity Mapper (SLIM) is a mm-wave line-intensity mapping (mm-LIM) experiment for the South Pole Telescope (SPT). The goal of SPT-SLIM is to serve as a techni…
SPT-SLIM: A Line Intensity Mapping Pathfinder for the South Pole Telescope
K. S. Karkare, A. J. Anderson, P. S. Barry +15
The South Pole Telescope Summertime Line Intensity Mapper (SPT-SLIM) is a pathfinder experiment that will demonstrate the use of on-chip filter-bank spectrometers for mm-wave line…
Event Horizon Telescope observations of the jet launching and collimation in Centaurus A
Michael Janssen, Heino Falcke, Matthias Kadler +236
Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimeter wavelengths have the power to reveal the launching and initial collimation region of e…
The Variability of the Black-Hole Image in M87 at the Dynamical Time Scale
Kaushik Satapathy, Dimitrios Psaltis, Feryal Ozel +235
The black-hole images obtained with the Event Horizon Telescope (EHT) are expected to be variable at the dynamical timescale near their horizons. For the black hole at the center o…
An Intensity Mapping Constraint on the CO-Galaxy Cross Power Spectrum at Redshift ~ 3
Ryan P. Keenan, Garrett K. Keating, Daniel P. Marrone
The abundance of cold molecular gas plays a crucial role in models of galaxy evolution. While deep spectroscopic surveys of CO emission lines have been a primary tool for measuring…
Rapid build-up of the stellar content in the protocluster core SPT234956 at
Ryley Hill, Scott Chapman, Kedar A. Phadke +22
The protocluster SPT234956 at contains one of the most actively star-forming cores known, yet constraints on the total stellar mass of this system are highly uncer…
Molecular Line Observations in Two Dusty Star-Forming Galaxies at z = 6.9
Sreevani Jarugula, Joaquin D. Vieira, Axel Weiß +18
SPT0311-58 is the most massive infrared luminous system discovered so far during the Epoch of Reionization (EoR). In this paper, we present a detailed analysis of the molecular int…
ALMA Observations of the Sub-kpc Structure of the Host Galaxy of a z= 6.5 Lensed Quasar: A Rotationally-Supported Hyper-Starburst System at the Epoch of Reionization
Minghao Yue, Jinyi Yang, Xiaohui Fan +11
We report ALMA observations of the dust continuum and {\cii} emission of the host galaxy of J0439+1634, a gravitationally lensed quasar at . Gravitational lensing boosts the…
Constraints on black-hole charges with the 2017 EHT observations of M87*
Prashant Kocherlakota, Luciano Rezzolla, Heino Falcke +234
Our understanding of strong gravity near supermassive compact objects has recently improved thanks to the measurements made by the Event Horizon Telescope (EHT). We use here the M8…
The Polarized Image of a Synchrotron Emitting Ring of Gas Orbiting a Black Hole
Ramesh Narayan, Daniel C. M. Palumbo, Michael D. Johnson +237
Synchrotron radiation from hot gas near a black hole results in a polarized image. The image polarization is determined by effects including the orientation of the magnetic field i…
Polarimetric properties of Event Horizon Telescope targets from ALMA
Ciriaco Goddi, Ivan Marti-Vidal, Hugo Messias +31
We present the results from a full polarization study carried out with ALMA during the first VLBI campaign, which was conducted in Apr 2017 in the 3mm and 1.3mm bands, in con…
