Unveiling the Bulge-Disc Structure, AGN Feedback, and Baryon Landscape in a Massive Spiral Galaxy with Mpc-Scale Radio Jets
Joydeep Bagchi, Shankar Ray, Suraj Dhiwar +9
This study delves into the bulge-disc components and stellar mass distribution in the fast-rotating, highly massive spiral galaxy 2MASX~J23453268-0449256, distinguished by extraord…
The InfraRed Imaging Spectrograph (IRIS) for TMT: latest science cases and simulations
Shelley A. Wright, Gregory Walth, Tuan Do +36
The Thirty Meter Telescope (TMT) first light instrument IRIS (Infrared Imaging Spectrograph) will complete its preliminary design phase in 2016. The IRIS instrument design includes…
Optical Identification of Quasar 0917+7122 in the Direction of an Extreme-Ultraviolet Source
Dan Maoz, Eran Ofek, Amotz Shemi +6
We report the optical identification of an mag, quasar at the position of a 6 cm radio source and a faint \rosat PSPC X-ray source. The quasar lies within the er…
A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): Broad-line AGN at revealed by JWST/NIRCam WFSS
Xiaojing Lin, Feige Wang, Xiaohui Fan +33
Low-luminosity AGNs with low-mass black holes (BHs) in the early universe are fundamental to understanding the BH growth and their co-evolution with the host galaxies. Utilizing JW…
Addressing Decadal Survey Science through Community Access to Highly Multiplexed Spectroscopy with BigBOSS on the KPNO Mayall Telescope
Caty Pilachowski, Carles Badenes, Stephen Bailey +87
This document summarizes the results of a community-based discussion of the potential science impact of the Mayall+BigBOSS highly multiplexed multi-object spectroscopic capability.…
Astro2020 Science White Paper: The Local Relics of of Supermassive Black Hole Seeds
Jenny E Greene, Aaron Barth, Andrea Bellini +18
We have compelling evidence for stellar-mass black holes (BHs) of ~5-80 M_sun that form through the death of massive stars. We also have compelling evidence for so-called supermass…
Spectropolarimetry and Modeling of the Eclipsing T Tauri Star KH 15D
Eric Agol, Aaron Barth, Sebastian Wolf +1
KH 15D is a strongly variable T Tauri star in the young star cluster NGC 2264 that shows a decrease in flux of 3.5 magnitudes lasting for 18 days and repeating every 48 days. The e…
Astro2020 Science White Paper: Black Holes Across Cosmic Time
Kayhan Gültekin, Aaron Barth, Karl Gebhardt +8
Supermassive black holes are located at the center of most, if not all, massive galaxies. They follow close correlations with global properties of their host galaxies (scaling rela…
Shedding the envelope: JWST reveals a kiloparsec-scale [OIII]-weak Balmer shell around a z=7.64 quasar
Julien Wolf, Eduardo Bañados, Xiaohui Fan +25
Luminous quasars at the redshift frontier z>7 serve as stringent probes of super-massive black hole formation and they are thought to undergo much of their growth obscured by dense…
The First Luminous Quasars and Their Host Galaxies
Xiaohui Fan, Aaron Barth, Eduardo Banados +26
The discovery of luminous quasars at redshifts up to 7.5 demonstrates the existence of several billion M_sun supermassive black holes (SMBHs) less than a billion years after the Bi…
Robotic reverberation mapping of the broad-line radio galaxy 3C 120
Michael Hlabathe, David Starkey, Keith Horne +10
We carried out photometric and spectroscopic observations of the well-studied broad-line radio galaxy 3C 120 with the Las Cumbres Observatory (LCO) global robotic telescope network…
Thirty Meter Telescope International Observatory Detailed Science Case 2024
Warren Skidmore, Bob Kirshner, David Andersen +168
The Thirty Meter Telescope (TMT) International Observatory (TIO) will be a revolutionary leap forward in astronomical observing capabilities, enabling us to address some of the mos…
