How do disks survive mergers?

PF Hopkins, TJ Cox, JD Younger… - The Astrophysical …, 2009 - iopscience.iop.org
We develop a general physical model for how galactic disks survive and/or are destroyed in
mergers and interactions. Based on simple dynamical arguments, we show that gas …

Mergers and bulge formation in λcDM: which mergers matter?

…, K Stewart, A Wetzel, JD Younger - The Astrophysical …, 2010 - iopscience.iop.org
We use a suite of semi-empirical models to predict the galaxy–galaxy merger rate and relative
contributions to bulge growth as a function of mass (both halo and stellar), redshift, and …

Intense star formation within resolved compact regions in a galaxy at z = 2.3

…, B Siana, G Siringo, DP Stark, D Wilner, JD Younger - Nature, 2010 - nature.com
Massive galaxies in the early Universe have been shown to be forming stars at surprisingly
high rates 1 , 2 , 3 . Prominent examples are dust-obscured galaxies which are luminous …

Mergers in ΛCDM: Uncertainties in theoretical predictions and interpretations of the merger rate

…, L Hernquist, K Stewart, JD Younger… - The Astrophysical …, 2010 - iopscience.iop.org
Different theoretical methodologies lead to order-of-magnitude variations in predicted galaxy–galaxy
merger rates. We examine how this arises and quantify the dominant uncertainties. …

Evidence for a population of high-redshift submillimeter galaxies from interferometric imaging

JD Younger, GG Fazio, JS Huang, MS Yun… - The Astrophysical …, 2007 - iopscience.iop.org
We have used the Submillimeter Array to image a flux-limited sample of seven submillimeter
galaxies, selected by the AzTEC camera on the JCMT at 1.1 mm, in the COSMOS field at …

The formation of high-redshift submillimetre galaxies

…, L Hernquist, P Jonsson, JD Younger… - Monthly Notices of …, 2010 - academic.oup.com
We describe a model for the formation of z∼ 2 submillimetre galaxies (SMGs) which
simultaneously accounts for both average and bright SMGs while providing a reasonable match to …

A physical model for z∼ 2 dust-obscured galaxies

…, PF Hopkins, B Groves, JD Younger… - Monthly Notices of …, 2010 - academic.oup.com
We present a physical model for the origin of z∼ 2 dust-obscured galaxies (DOGs), a class
of high-redshift ultraluminous infrared galaxies (ULIRGs) selected at 24 μm which are …

Mergers, active galactic nuclei and 'normal'galaxies: contributions to the distribution of star formation rates and infrared luminosity functions

PF Hopkins, JD Younger, CC Hayward… - Monthly Notices of …, 2010 - academic.oup.com
We use a novel method to predict the contribution of normal star-forming galaxies, merger-induced
bursts and obscured active galactic nuclei (AGN), to infrared luminosity functions (LFs…

Tocolysis: Present and future treatment options

JD Younger, E Reitman, G Gallos - Seminars in perinatology, 2017 - Elsevier
In the United States, the generally accepted indication for tocolytic therapy centers on
suppression of preterm labor. This may be in the form of preventative therapy with progesterone in …

Antitruncated stellar disks via minor mergers

JD Younger, TJ Cox, AC Seth… - The Astrophysical …, 2007 - iopscience.iop.org
We use hydrodynamic simulations of minor mergers of galaxies to investigate the nature of
surface brightness excesses at large radii observed in some spiral galaxies: antitruncated …
