The ACS LCID project. IX. Imprints of the early Universe in the radial variation of the star formation history of dwarf galaxies
Sebastian L. Hidalgo, Matteo Monelli, Antonio Aparicio +8
Based on Hubble Space Telescope observations from the Local Cosmology from Isolated Dwarfs project, we present the star formation histories, as a function of galactocentric radius,…
A study of fundamental limitations to statistical detection of redshifted HI from the epoch of reionization
Nithyanandan Thyagarajan, N. Udaya Shankar, Ravi Subrahmanyan +46
In this paper we explore for the first time the relative magnitudes of three fundamental sources of uncertainty, namely, foreground contamination, thermal noise and sample variance…
A Herschel-ATLAS study of dusty spheroids: probing the minor-merger process in the local Universe
S. Kaviraj, K. Rowlands, M. Alpaslan +7
We use multi-wavelength (0.12 - 500 micron) photometry from Herschel-ATLAS, WISE, UKIDSS, SDSS and GALEX, to study 23 nearby spheroidal galaxies with prominent dust lanes (DLSGs).…
Interstellar scintillation is an indicator of astrometric stability
Robert Schaap, Stanislav Shabala, Simon Ellingsen +2
We examine the relationship between astrometric stability and astrophysical properties in flat-spectrum radio-loud quasars making up the celestial reference frame. We use position…
A 189 MHz, 2400 square degree polarization survey with the Murchison Widefield Array 32-element prototype
G. Bernardi, L. J. Greenhill, D. A. Mitchell +50
We present a Stokes I, Q and U survey at 189 MHz with the Murchison Widefield Array 32-element prototype covering 2400 square degrees. The survey has a 15.6 arcmin angular resoluti…
The effects of frequency-dependent quasar variability on the celestial reference frame
Stanislav Shabala, Jonathan Rogers, Jamie McCallum +4
We examine the relationship between source position stability and astrophysical properties of radio-loud quasars making up the International Celestial Reference Frame. Understandin…
