Imaging the cool gas, dust, star formation, and AGN in the first galaxies
C. L. Carilli, S. Myers, P. Appleton +16
When, and how, did the first galaxies and supermassive black holes (SMBH) form, and how did they reionization the Universe? First galaxy formation and cosmic reionization are among…
The Star Formation Rate - Dense Gas Relation in Galaxies as Measured by HCN (3-2) Emission
R. S. Bussmann, D. Narayanan, Y. L. Shirley +6
We present observations made with the 10m Heinrich Hertz Sub-Millimeter Telescope of HCN (3-2) emission from a sample of 30 nearby galaxies ranging in infrared luminosity from 10^1…
Molecular Star Formation Rate Indicators in Galaxies
Desika Narayanan, Thomas J. Cox, Yancy Shirley +3
We derive a physical model for the observed relations between star formation rate (SFR) and molecular line (CO and HCN) emission in galaxies, and show how these observed relations…
The Role of Galactic Winds on Molecular Gas Emission from Galaxy Mergers
Desika Narayanan, T. J. Cox, Brandon Kelly +7
We assess the impact of starburst and AGN feedback-driven winds on the CO emission from galaxy mergers, and, in particular, search for signatures of these winds in the simulated CO…
The Nature of CO Emission From z~6 Quasars
Desika Narayanan, Yuexing Li, Thomas J. Cox +9
We investigate the nature of CO emission from z~6 quasars by combining non-LTE radiative transfer calculations with merger-driven models of z~6 quasar formation that arise naturall…
Simulated Molecular Gas Emission in Galaxy Mergers with Embedded AGN
Desika Narayanan, Thomas J. Cox, Brant Robertson +6
We investigate the effect of embedded active galactic nuclei (AGN) in galaxy mergers on the CO molecular line emission by combining non-local thermodynamic equilibrium (LTE) radiat…
