Properties of M31. II: A Cepheid disk sample derived from the first year of PS1 PAndromeda data
Mihael Kodric, Arno Riffeser, Ulrich Hopp +14
We present a sample of Cepheid variable stars towards M31 based on the first year of regular M31 observations of the PS1 survey in the r_P1 and i_P1 filters. We describe the select…
The Araucaria Project: The Distance to the Sculptor Group Galaxy NGC 247 from Cepheid Variables Discovered in a Wide-Field
A. Garcia-Varela, G. Pietrzynski, W. Gieren +9
We report on the discovery of a Cepheid population in the Sculptor Group spiral galaxy NGC 247 for the first time. On the basis of wide-field images collected in photometric survey…
Discovery of a young massive stellar cluster near HESS J1813-178
Maria Messineo, Donald F. Figer, Ben Davies +3
We present the serendipitous discovery of a young stellar cluster in the Galactic disk at l=12deg. Using Keck/NIRSPEC, we obtained high- and low-resolution spectroscopy of several…
The Araucaria Project: VLT-spectroscopy of blue massive stars in NGC 55
N. Castro, A. Herrero, M. Garcia +6
This is the first paper of a series devoted to studying the population of blue massive stars in NGC 55, a galaxy of the Sculptor group at a distance of about 2 Mpc. We have obtaine…
The Araucaria Project. The Distance to the Local Group Galaxy WLM from Near-Infrared Photometry of Cepheid Variables
W. Gieren, G. Pietrzynski, O. Szewczyk +5
We have obtained deep images in the near-infrared J and K filters for several fields in the Local Group galaxy WLM. We report intensity mean magnitudes for 31 Cepheids located in t…
The Araucaria Project. The Distance to the Sculptor dwarf spheroidal galaxy from infrared photometry of RR Lyrae stars
G. Pietrzynski, W. Gieren, O. Szewczyk +8
We have obtained single-phase near-infrared magnitudes in the J and K bands for a sample of 78 RR Lyrae stars in the Sculptor dSph galaxy. Applying different theoretical and empiri…
