The SAMI - Fornax Dwarfs Survey III: Evolution of[α/Fe] in dwarfs, from Galaxy Clusters to the Local Group
Juan Manuel Romero-Gomez,Reynier Peletier,J. A. L. Aguerri,Steffen Mieske,Nicholas Scott,Joss Bland-Hawthorn,Julia J. Bryant,Scott M. Croom,J. Falc'on-Barroso,Michael Hilker,G. van de Ven,Aku Venhola +11 more
TL;DR: In this paper , the stellar population properties of a sample of dwarf galaxies in the Fornax Cluster, down to a stellar mass of 107 M⊙, were studied using very deep, high spectral resolution data from the SAMI Integral Field Spectrograph.
Journal ArticleDOI
The New Galaxy: Signatures of its Formation
TL;DR: A detailed physical picture where individual stellar populations can be associated with (tagged to) elements of the protocloud is far beyond our current understanding as mentioned in this paper, and we have only a crude picture of how galaxies like our own came into existence.
Journal ArticleDOI
Seeking celestial positronium with an OH-suppressed diffraction-limited spectrograph.
J. Gordon Robertson,Simon Ellis,Qingshan Yu,Joss Bland-Hawthorn,Christopher H. Betters,Martin M. Roth,Sergio G. Leon-Saval +6 more
TL;DR: In this article, a diffraction-limited spectroscopic system using novel photonic components (a photonic lantern, OH fiber Bragg grating filters, and a photonic TIGER 2D pseudo-slit) was used to observe the Ps Balmer alpha line at 1.3122 µm.
Journal ArticleDOI
Estimation of the Tilt of the Stellar Velocity Ellipsoid from RAVE and Implications for Mass Models
Arnaud Siebert,Olivier Bienaymé,James Binney,Joss Bland-Hawthorn,Randy D. Campbell,Kenneth C. Freeman,Brad K. Gibson,Gerard Gilmore,Eva K. Grebel,Amina Helmi,Ulisse Munari,Julio F. Navarro,Quentin A. Parker,George M. Seabroke,George M. Seabroke,Alessandro Siviero,Matthias Steinmetz,Mary E K Williams,Rosemary F. G. Wyse,Tomaž Zwitter +19 more
TL;DR: In this article, the authors measured the inclination of the velocity ellipsoid at 1 kpc below the Galactic plane using a sample of red clump giants from the RAVE DR2 release.
Journal ArticleDOI
Three-Dimensional Simulations of a Starburst-Driven Galactic Wind
TL;DR: In this paper, a series of three-dimensional simulations of a starburst-driven wind in an inhomogeneous interstellar medium is performed, and it is shown that soft X-ray emission arises from gas that has been mass-loaded from clouds in the disk, as well as from bow shocks upstream of clouds, driven into the flow by the ram pressure of the wind, and the interaction between these shocks.
