Detection of a distinct metal-poor stellar halo in the early-type galaxy NGC 3115
Mark B. Peacock, Jay Strader, Aaron J. Romanowsky +1
We present the resolved stellar populations in the inner and outer halo of the nearby lenticular galaxy NGC~3115. Using deep HST observations, we analyze stars two magnitudes faint…
Low Mach Number Fluctuating Hydrodynamics of Multispecies Liquid Mixtures
A. Donev, A. J. Nonaka, A. K. Bhattacharjee +2
We develop a low Mach number formulation of the hydrodynamic equations describing transport of mass and momentum in a multispecies mixture of incompressible miscible liquids at spe…
VEGAS-SSS. A VST survey of elliptical galaxies in the southern hemisphere: analysis of small stellar systems. Testing the methodology on the globular cluster system in NGC3115
Michele Cantiello, Massimo Capaccioli, Nicola Napolitano +11
We present a study of globular clusters (GCs) and other small stellar systems (SSSs) in the field of NGC3115, observed as part of the VEGAS imaging survey, carried out with the VST…
Unit Quaternions and the Bloch Sphere
K. B. Wharton, D. Koch
The spinor representation of spin-1/2 states can equally well be mapped to a single unit quaternion, yielding a new perspective despite the equivalent mathematics. This paper first…
Searching for stochastic gravitational waves using data from the two co-located LIGO Hanford detectors
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +873
Searches for a stochastic gravitational-wave background (SGWB) using terrestrial detectors typically involve cross-correlating data from pairs of detectors. The sensitivity of such…
The SLUGGS survey: Globular cluster stellar population trends from weak absorption lines in stacked spectra
Christopher Usher, Duncan A. Forbes, Jean P. Brodie +7
As part of the SLUGGS survey, we stack 1137 Keck DEIMOS spectra of globular clusters from 10 galaxies to study their stellar populations in detail. The stacked spectra have median…
