Investigating the [C]-to-H conversion factor and the H gas budget of galaxies at with hydrodynamical simulations
David Vizgan, Kasper E. Heintz, Thomas R. Greve +5
One of the most fundamental baryonic matter components of galaxies is the neutral atomic hydrogen (H). At low redshifts, this component can be traced directl…
Tracing Molecular Gas in z 6 Galaxies with [C]
David Vizgan, Thomas R. Greve, Karen P. Olsen +7
We investigate the fine-structure [C] line at m as a molecular gas tracer by analyzing the relationship between molecular gas mass () and…
VERTICO: The Virgo Environment Traced In CO Survey
Toby Brown, Christine D. Wilson, Nikki Zabel +33
We present the Virgo Environment Traced in CO (VERTICO) survey, a new effort to map CO(), CO(), and CO() in 51 Virgo Cluster galaxies with the A…
Revisiting the [C II] line-intensity mapping power spectrum from the EoR using non-uniform line-luminosity scatter
Chandra Shekhar Murmu, Karen P. Olsen, Thomas R. Greve +9
Detecting the line-intensity mapping (LIM) signal from the galaxies of the Epoch of Reionization is an emerging tool to constrain their role in reionization. Ongoing and upcoming e…
An Empirical Determination of the Dependence of the Circumgalactic Mass Cooling Rate and Feedback Mass Loading Factor on Galactic Stellar Mass
Huanian Zhang, Dennis Zaritsky, Karen Pardos Olsen +9
Using our measurements of the H emission line flux originating in the cool (T K) gas that populates the halos of galaxies, we build a joint model to describe mass of…
SIGAME v3: Gas Fragmentation in Post-processing of Cosmological Simulations for More Accurate Infrared Line Emission Modeling
Karen Pardos Olsen, Blakesley Burkhart, Mordecai-Mark Mac Low +9
We present an update to the framework called SImulator of GAlaxy Millimeter/submillimeter Emission (SÍGAME). SÍGAME derives line emission in the far-infrared (FIR) for galaxies in…
Predictions of the L-SFR and [C] Luminosity Function at the Epoch of Reionization
T. K. Daisy Leung, Karen P. Olsen, Rachel S. Somerville +5
We present the first predictions for the - SFR relation and [CII] luminosity function (LF) in the Epoch of Reionization (EoR) based on cosmological hydrodynamics si…
Challenges and Techniques for Simulating Line Emission
Karen P. Olsen, Andrea Pallottini, Aida Wofford +9
Modeling emission lines from the millimeter to the UV and producing synthetic spectra is crucial for a good understanding of observations, yet it is an art filled with hazards. Thi…
SIGAME simulations of the [CII], [OI] and [OIII] line emission from star forming galaxies at z ~ 6
K. P. Olsen, T. R. Greve, D. Narayanan +4
Of the almost 40 star forming galaxies at z>~5 (not counting QSOs) observed in [CII] to date, nearly half are either very faint in [CII], or not detected at all, and fall well belo…
Observing and Simulating Galaxy Evolution - from X-ray to Millimeter Wavelengths
Karen P. Olsen
What main mechanisms set the star formation rate (SFR) of galaxies? This PhD thesis is a quest into the influences of gas and active galactic nuclei (AGNs) on the SFR, with particu…
Simulator of Galaxy Millimeter/Submillimeter Emission (SIGAME): The [CII]-SFR Relationship of Massive z=2 Main Sequence Galaxies
Karen P. Olsen, Thomas R. Greve, Desika Narayanan +3
We present SÍGAME simulations of the [CII]157.7 fine structure line emission from cosmological smoothed particle hydrodynamics (SPH) simulations of seven main sequence galaxies…
SImulator of GAlaxy Millimetre/submillimetre Emission (SIGAME): CO emission from massive z=2 main-sequence galaxies
Karen P. Olsen, Thomas R. Greve, Christian Brinch +4
We present SIGAME (SImulator of GAlaxy Millimetre/submillimetre Emission), a new numerical code designed to simulate the 12CO rotational line emission spectrum of galaxies. Using s…
Evidence for Widespread AGN Activity among Massive Quiescent Galaxies at z ~ 2
Karen Pardos Olsen, Jesper Rasmussen, Sune Toft +1
We quantify the presence of Active Galactic nuclei (AGN) in a mass-complete (M_* >5e10 M_sun) sample of 123 star-forming and quiescent galaxies at 1.5 < z < 2.5, using X-ray data f…
