Mapping the Galactic Halo VIII: Quantifying substructure
Else Starkenburg, Amina Helmi, Heather L. Morrison +11
We have measured the amount of kinematic substructure in the Galactic halo using the final data set from the Spaghetti project, a pencil-beam high latitude sky survey. Our sample c…
A Study of the Type II-P Supernova 2003gd in M74
M. A. Hendry, S. J. Smartt, J. R. Maund +18
We present photometric and spectroscopic data of the type II-P supernova 2003gd, which was discovered in M74 close to the end of its plateau phase. SN 2003gd is the first type II s…
Neutral Hydrogen and Star Formation in the Irregular Galaxy NGC 2366
D. A. Hunter, B. G. Elmegreen, H. van Woerden
We present UBVJHKHalpha and HI data of the irregular galaxy NGC 2366. It is a normal boxy-shaped disk seen at high inclination angle. We do not see any unambiguous observational si…
HI spectra and column densities toward HVC and IVC probes
B. P. Wakker, P. M. W. Kalberla, H. van Woerden +2
We show 21-cm line profiles in the direction of stars and extragalactic objects, lying projected on high- and intermediate-velocity clouds (HVCs and IVCs). About half of these are…
A confirmed location in the Galactic halo for the high-velocity cloud 'chain A'
Hugo van Woerden, Ulrich J. Schwarz, Reynier F. Peletier +2
The high-velocity clouds of atomic hydrogen, discovered about 35 years ago, have velocities inconsistent with simple Galactic rotation models that generally fit the stars and gas i…
