(Royal Astronomical SocietyOxford University Press, 2011)Encoded within the morphological structure of galaxies are clues related to their formation and evolutionary history. Recent advances pertaining to the statistics of galaxy morphology include sophisticated measures of ...
-
(Oxford University Press, 2014-01-10)We use the Galaxies-Intergalactic Medium Interaction Calculation (GIMIC) cosmological hydrodynamic simulation at z = 0 to study the distribution and environmental dependence of neutral hydrogen (H I) gas in the outskirts ...
-
(Springer Netherlands, 2018-05-22)This study’s objective was to exploit infrared VVV (VISTA Variables in the Via Lactea) photometry for high latitude RRab stars to establish an accurate Galactic Centre distance. RRab candidates were discovered ...
-
(American Astronomical SocietyIOP Publishing, 2012-05)The Next Generation Virgo Cluster Survey (NGVS) is a program that uses the 1 deg[superscript 2] MegaCam instrument on the Canada–France–Hawaii Telescope to carry out a comprehensive optical imaging survey of the Virgo ...
-
(American Astronomical SocietyIOP Publishing, 2014-12-20)The Next Generation Virgo Cluster Survey (NGVS) is an optical imaging survey covering 104 deg[superscript 2] centered on the Virgo cluster. Currently, the complete survey area has been observed in the u[superscript ∗] giz ...
-
(Halifax, N.S. : Saint Mary's University, 2018)Utilizing new ALMA-ACA observations of the [N II] 205 µm line in combination with existing [C II] 158 µm observations, we characterize the L[C II]/L[N II] distribution in highredshift ...
-
(Halifax, N.S. : Saint Mary's University, 2001)The IRAM 30m telescope has been used to observe the J = 1-0 transition of [superscript 12]CO at several positions along the central dust lane of NGC 5866. The data were used to determine the large-scale properties of the ...

Stars, dust, and the growth of ultraviolet-selected sub-L[superscript ∗] galaxies at redshift z ∼ 2 (Oxford University PressRoyal Astronomical Society, 2012)This work concerns the physical properties of very faint (R[subscript lim] = 28 AB mag; M[subscript stars,lim] ∼ 10[superscript 8] M[subscript circled dot]), ultraviolet-selected (UV-selected) sub-L[superscript ∗] BX ...
-
(American Astronomical SocietyIOP Publishing, 2009-03-01)We present the results of spectral energy distribution (SED) fitting analysis for Lyman break galaxies (LBGs) at z ∼ 5 in the Great Observatories Origins Deep Survey North (GOODS-N) and its flanking fields (the GOODS-FF). ...
-
(Oxford University PressRoyal Astronomical Society, 2019-03-20)We report the discovery of RX J2317.8–4422 in an extremely low X-ray flux state by the Neil Gehrels Swift observatory in 2014 April/May. In total, the low-energy X-ray emission dropped by a factor of 100. ...
-
(Halifax, N.S. : Saint Mary's University, 2017)The determination of galaxy masses is an essential tool for our understanding of galaxy evolution. Looking at 67 local galaxies, we find that galaxy stellar masses are underestimated using traditional methods that assume ...
-
(American Astronomical SocietyIOP Publishing, 2010-10-01)We explore the feasibility and limitations of using the 1.6 [micron]m bump as a photometric redshift indicator and selection technique, and use it to study the rest-frame H-band galaxy luminosity and stellar mass functions ...
-
(Oxford University Press, 2012-08)The VISTA Magellanic Cloud (VMC; PI: M.-R. L. Cioni) survey is collecting deep Ks-band time series photometry of the pulsating variable stars hosted by the system formed by the two Magellanic Clouds (MCs) and ...
