An Imaging and Spectroscopic Exploration of the Dusty Compact Obscured Nucleus Galaxy Zw 049.057

open access: yesThe Astrophysical Journal Supplement Series
Zw 049.057 is a moderate-mass, dusty, early-type galaxy that hosts a powerful compact obscured nucleus (CON, L _FIR,CON ≥ 10 ^11 L _⊙ ). The resolution of the Hubble Space Telescope enabled measurements of the stellar light distribution and ...

A Direct Detection of Gas Accretion: The Lyman Limit System in 3C 232

open access: yes, 2010
The gas added and removed from galaxies over cosmic time greatly affects their stellar populations and star formation rates. QSO absorption studies in close QSO/galaxy pairs create a unique opportunity to study the physical conditions and kinematics of ...

WFC3 grism confirmation of the distant cluster Cl J1449+0856 at z=2.00: Quiescent and star-forming galaxy populations

open access: yes, 2013
We present deep Hubble Space Telescope Wide Field Camera 3 slitless spectroscopic observations of the distant cluster Cl J1449+0856. These cover a single pointing with 18 orbits of G141 spectroscopy and F140W imaging, allowing us to derive secure ...

Deciphering Gas Dynamics and Star Formation in a z = 1.1 Main-sequence Spiral Galaxy with ALMA and JWST

open access: yesThe Astrophysical Journal
We present a joint analysis of high-resolution CO(2–1) and Paschen- α (Pa α ) emission lines to trace gas dynamics and spatially resolved star formation in ASPECS-LP.3 mm.06, a z = 1.1 main-sequence galaxy.

The kinematics of ionized gas in lyman-break analogs at z ~ 0.2 [PDF]

open access: yes, 2010
We present results for 19 “Lyman-break analogs” observed with Keck/OSIRIS with an adaptive-optics-assisted spatial resolution of less than 200 pc. We detect satellites/companions, diffuse emission, and velocity shear, all with high signal-to-noise ...

Mosfire Spectroscopy Of Galaxies In Cosmic Noon

open access: yes, 2017
The recent development of sensitive, multiplexed near infra-red instruments has presented astronomers the unique opportunity to survey mass/magnitude complete samples of galaxies at Cosmic Noon, a time period where ∼ 80% of the observed baryonic mass is generated and galaxies are actively star-forming and evolving rapidly.

HerS-3: An Exceptional Einstein Cross Reveals a Massive Dark Matter Halo

open access: yesThe Astrophysical Journal
We present a study of HerS-3, a dusty star-forming galaxy at z _spec  = 3.0607, which is gravitationally amplified into an Einstein cross with a fifth image of the background galaxy seen at the center of the cross.

ISO spectroscopy of luminous galaxies

open access: yes, 2016
Spectroscopy with SWS and ISOPHOT-S has opened a new window for studies of the nuclei of external galaxies. We present selected results of observations of starburst galaxies and active galactic nuclei and discuss the mid-infrared extinction law. The flux ratio of high and low excitation fine structure lines and the strength of the 'PAH' emission ...
