The Dawning of the Stream of Aquarius in RAVE
Mary E. K. Williams, Matthias Steinmetz, Sanjib Sharma +22
We identify a new, nearby (0.5 < d < 10 kpc) stream in data from the RAdial Velocity Experiment (RAVE). As the majority of stars in the stream lie in the constellation of Aquarius…
Detection of a radial velocity gradient in the extended local disc with RAVE
A. Siebert, B. Famaey, I. Minchev +22
Using a sample of 213,713 stars from the Radial Velocity Experiment (RAVE) survey, limited to a distance of 2 kpc from the Sun and to |z|<1 kpc, we report the detection of a veloci…
Towards a new full-sky list of radial velocity standard stars
F. Crifo, G. Jasniewicz, C. Soubiran +4
The calibration of the Radial Velocity Spectrometer (RVS) onboard the ESA Gaia satellite (to be launched in 2012) requires a list of standard stars with a radial velocity (RV) know…
Structure in phase space associated with spiral and bar density waves in an N-body galactic disk
Alice C. Quillen, Jamie Dougherty, Micaela B. Bagley +2
An N-body hybrid simulation, integrating both massive and tracer particles, of a Galactic disk is used to study the stellar phase space distribution or velocity distributions in di…
Radial Mixing due to Spiral-Bar Resonance Overlap: Implications to the Milky Way
I. Minchev, B. Famaey
We have recently identified a previously unknown radial migration mechanism resulting from the overlap of spiral and bar resonances in galactic discs (Minchev & Famaey 2010, Minche…
Testing formation mechanisms of the Milky Way's thick disc with RAVE
Michelle Wilson, Amina Helmi, H. L. Morrison +21
We study the eccentricity distribution of a thick disc sample of stars observed in the Radial Velocity Experiment (RAVE) and compare it to that expected in four simulations of thic…
Rapid Intrinsic Variability of Sgr A* at Radio Wavelengths
F. Yusef-Zadeh, M. Wardle, J. Miller-Jones +3
Sgr A* exhibits flares in radio, millimeter and submm wavelengths with durations of hour. Using structure function, power spectrum and autocorrelation function analysis, w…
The two states of Sgr A* in the near-infrared: bright episodic flares on top of low-level continuous variability
K. Dodds-Eden, S. Gillessen, T. K. Fritz +11
In this paper we examine properties of the variable source Sgr A* in the near-infrared (NIR) using a very extensive Ks-band data set from NACO/VLT observations taken 2004 to 2009.…
The Northern wraps of the Sagittarius Stream as traced by Red Clump stars: distances, intrinsic widths and stellar densities
M. Correnti, M. Bellazzini, R. A. Ibata +2
We trace the tidal Stream of the Sagittarius dwarf spheroidal galaxy (Sgr dSph) using Red Clump stars from the catalog of the Sloan Digital Sky Survey - Data Release 6, in the rang…
The Herschel first look at protostars in the Aquila Rift
S. Bontemps, Ph. Andre, V. Konyves +40
As part of the science demonstration phase of the Herschel mission of the Gould Belt Key Program, the Aquila Rift molecular complex has been observed. The complete ~ 3.3deg x 3.3de…
Herschel photometric observations of the low metallicity dwarf galaxy NGC 1705
B. O'Halloran, M. Galametz, S. C. Madden +57
We present Herschel SPIRE and PACS photometeric observations of the low metallicity (Z ~ 0.35 solar) nearby dwarf galaxy, NGC 1705, in six wavelength bands as part of the Dwarf Gal…
The central region of spiral galaxies as seen by Herschel. M81, M99 and M100
M. Sauvage, N. Sacchi, G. J. Bendo +57
With appropriate spatial resolution, images of spiral galaxies in thermal infrared (~10 micron and beyond) often reveal a bright central component, distinct from the stellar bulge,…
Time Dependent Models of Flares from Sagittarius A*
Katie Dodds-Eden, Prateek Sharma, Eliot Quataert +4
The emission from Sgr A*, the supermassive black hole in the Galactic Center, shows order of magnitude variability ("flares") a few times a day that is particularly prominent in th…
X-ray and multiwavelength view of NGC 4278. A LINER-Seyfert connection?
G. Younes, D. Porquet, B. Sabra +3
(Abridged) Based on UV to X-ray and radio to UV flux ratios, some argue that low ionization emission line regions (LINERs) and low luminosity AGN (LLAGN) are a scaled-down version…
Halo globular clusters observed with AAOmega: dark matter content, metallicity and tidal heating
Richard R. Lane, László L. Kiss, Geraint F. Lewis +6
Globular clusters have proven to be essential to our understanding of many important astrophysical phenomena. Here we analyse spectroscopic observations of ten Halo globular cluste…
Multi-Wavelength Study of Sgr A*: The Short Time Scale Variability
F. Yusef-Zadeh, J. Miller-Jones, D. Roberts +5
To understand the correlation and the radiation mechanism of flare emission in different wavelength bands, we have coordinated a number of telescopes to observe SgrA* simultaneousl…
Distance determination for RAVE stars using stellar models
M. A. Breddels, M. C. Smith, A. Helmi +21
(Abridged) Aims:We develop a method for deriving distances from spectroscopic data and obtaining full 6D phase-space coordinates for the RAVE survey's second data release. Methods:…
Flares from Sgr A* and their emission mechanism
K. Dodds-Eden, D. Porquet, G. Trap +12
We summarize recent observations and modeling of the brightest Sgr A* flare to be observed simultaneously in (near)-infrared and X-rays to date. Trying to explain the spectral char…
AAOmega Observations of 47 Tucanae: Evidence for a Past Merger?
Richard R. Lane, Brendon J. Brewer, László L. Kiss +6
The globular cluster 47 Tucanae is well studied but it has many characteristics that are unexplained, including a significant rise in the velocity dispersion profile at large radii…
