The propagation of uncertainties in stellar population synthesis modeling III: model calibration, comparison, and evaluation (2009)

Conroy, Charlie, Gunn, James E.

Stellar population synthesis (SPS) provides the link between the stellar and dust content of galaxies and their observed spectral energy distributions. In the present work we perform a comprehensive...

Dust attenuation in the restframe ultraviolet: constraints from star-forming galaxies at z~1 (2009)

Conroy, Charlie

A novel technique is employed for estimating attenuation curves in galaxies where only photometry and spectroscopic redshifts are available. This technique provides a powerful measure of particular...

The propagation of uncertainties in stellar population synthesis modeling II: The challenge of comparing galaxy evolution models to observations (2009)

Conroy, Charlie, White, Martin, Gunn, James E.

Models for the formation and evolution of galaxies readily predict physical properties such as the star formation rates, metal enrichment histories, and, increasingly, gas and dust content of...

The propagation of uncertainties in stellar population synthesis modeling I: The relevance of uncertain aspects of stellar evolution and the IMF to the derived physical properties of galaxies (2008)

Conroy, Charlie, Gunn, James E., White, Martin

The stellar masses, mean ages, metallicities, and star formation histories of galaxies are now commonly estimated via stellar population synthesis (SPS) techniques. SPS relies on stellar evolution...

Connecting Galaxies, Halos, and Star Formation Rates Across Cosmic Time (2008)

Conroy, Charlie, Wechsler, Risa H.

A simple, observationally-motivated model is presented for understanding how halo masses, galaxy stellar masses, and star formation rates are related, and how these relations evolve with time. The...

The Void Phenomenon Explained (2008)

Tinker, Jeremy L., Conroy, Charlie

We use high-resolution N-body simulations, combined with a halo occupation model of galaxy bias, to investigate voids in the galaxy distribution. Our goal is to address the 'void phenomenon' of...

Thermal Balance in the Intracluster Medium: Is AGN Feedback Necessary? (2007)

Conroy, Charlie, Ostriker, Jeremiah P.

A variety of physical heating mechanisms are combined with radiative cooling to explore, via one dimensional hydrodynamic simulations, the expected thermal properties of the intracluster medium (ICM)...

The Varied Fates of z~2 Star-forming Galaxies (2007)

Conroy, Charlie, Shapley, Alice E., Tinker, Jeremy L., Santos, Michael R., Lemson, Gerard

Star-forming galaxies constitute the majority of galaxies with stellar masses >10^10 M_Sun/h^2 at z~2 and dominate the star-formation rate density of the Universe at this early epoch. It is thus...

Void Statistics in Large Galaxy Redshift Surveys: Does Halo Occupation of Field Galaxies Depend on Environment? (2007)

Tinker, Jeremy L., Conroy, Charlie, Norberg, Peder, Patiri, Santiago G., Weinberg, David H., Warren, Michael S.

We use measurements of the projected galaxy correlation function w_p and galaxy void statistics to test whether the galaxy content of halos of fixed mass is systematically different in low density...

Constraints on the merging timescale of luminous red galaxies, or, where do all the halos go? (2007)

Conroy, Charlie, Ho, Shirley, White, Martin

In the LCDM cosmology dark matter halos grow primarily through the accretion of smaller halos. Much of the mass in a halo of 10^14Msun comes in through accretion of ~10^13Msun halos. If each such...

The Hierarchical Build-Up of Massive Galaxies and the Intracluster Light since z=1 (2007)

Conroy, Charlie, Wechsler, Risa H., Kravtsov, Andrey V.

We use a set of simulation-based models for the dissipationless evolution of galaxies since z=1 to constrain the fate of accreted satellites embedded in dark matter subhalos. These models assign...

Evolution in the halo masses of isolated galaxies between z similar to 1 and z similar to 0: from DEEP2 to SDSS (2007)

Conroy, Charlie, Prada, Francisco, Newman, Jeffrey A., Croton, Darren, Coil, Alison L., Conselice, Christopher J., ...

We measure the evolution in the virial mass-to-light ratio (M 200/LB) and virial-to-stellar mass ratio (M 200/M*) for isolated ∼L* galaxies between z ∼ 1 and z ∼ 0 by combining data...

Evolution in the Halo Masses of Isolated Galaxies between z~1 and z~0: From DEEP2 to SDSS (2006)

Conroy, Charlie, Prada, Francisco, Newman, Jeffrey A., Croton, Darren, Coil, Alison L., Conselice, Christopher J., ...

We measure the evolution in the virial mass-to-light ratio (M_{200}/L_B) and virial-to-stellar mass ratio (M_{200}/M_\ast) for isolated ~ L* galaxies between z~1 and z~0 by combining data from the...

Modeling Luminosity-Dependent Galaxy Clustering Through Cosmic Time (2005)

Conroy, Charlie, Wechsler, Risa H., Kravtsov, Andrey V.

We employ high-resolution dissipationless simulations of the concordance LCDM cosmology to model the observed luminosity dependence and evolution of galaxy clustering through most of the age of the...

The DEEP2 Galaxy Redshift Survey: The Evolution of Void Statistics from z~1 to z~0 (2005)

Conroy, Charlie, Coil, Alison L., White, Martin, Newman, Jeffrey A., Yan, Renbin, Cooper, Michael C., ...

We present measurements of the void probability function (VPF) at z~1 using data from the DEEP2 Redshift Survey and its evolution to z~0 using data from the Sloan Digital Sky Survey (SDSS). We...

The DEEP2 Galaxy Redshift Survey: First results on galaxy groups (2004)

Gerke, Brian F., Newman, Jeffrey A., Davis, Marc, Marinoni, Christian, Yan, Renbin, Coil, Alison, ...

We use the first 25% of the DEEP2 Galaxy Redshift Survey spectroscopic data to identify groups and clusters of galaxies in redshift space. The data set contains 8370 galaxies with confirmed redshifts...

The DEEP2 Galaxy Redshift Survey: Probing the Evolution of Dark Matter Halos around Isolated Galaxies at z ~ 1 (2004)

Conroy, Charlie, Newman, Jeffrey A., Davis, Marc, Coil, Alison L., Yan, Renbin, Cooper, Michael C., ...

Using the first 25% of DEEP2 Redshift Survey data, we probe the line-of-sight velocity dispersion profile for isolated galaxies with absolute B-band magnitude -22
