Future Prospects: Deep Imaging of Galaxy Outskirts using Telescopes Large and Small
Roberto Abraham, Pieter van Dokkum, Charlie Conroy +5
The Universe is almost totally unexplored at low surface brightness levels. In spite of great progress in the construction of large telescopes and improvements in the sensitivity o…
A massive, quiescent, population II galaxy at a redshift of 2.1
Mariska Kriek, Charlie Conroy, Pieter G. van Dokkum +7
Unlike spiral galaxies such as the Milky Way, the majority of the stars in massive elliptical galaxies were formed in a short period early in the history of the Universe. The durat…
The Initial Mass Function in the Nearest Strong Lenses from SNELLS: Assessing the Consistency of Lensing, Dynamical, and Spectroscopic Constraints
Andrew B. Newman, Russell J. Smith, Charlie Conroy +2
We present new observations of the three nearest early-type galaxy (ETG) strong lenses discovered in the SINFONI Nearby Elliptical Lens Locator Survey (SNELLS). Based on their lens…
The Stellar Initial Mass Function in Early-Type Galaxies From Absorption Line Spectroscopy. IV. A Super-Salpeter IMF in the center of NGC 1407 from Non-Parametric Models
Charlie Conroy, Pieter van Dokkum, Alexa Villaume
It is now well-established that the stellar initial mass function (IMF) can be determined from the absorption line spectra of old stellar systems, and this has been used to measure…
Nebular Continuum and Line Emission in Stellar Population Synthesis Models
Nell Byler, Julianne J. Dalcanton, Charlie Conroy +1
Accounting for nebular emission when modeling galaxy spectral energy distributions (SEDs) is important, as both line and continuum emission can contribute significantly to the tota…
The Stellar Initial Mass Function in Early-Type Galaxies from Absorption Line Spectroscopy. III. Radial Gradients
Pieter van Dokkum, Charlie Conroy, Alexa Villaume +2
There is good evidence that the centers of massive early-type galaxies have a bottom-heavy stellar initial mass function (IMF) compared to the IMF of the Milky Way. Here we study t…
