VLT/FORS1 spectrophotometry of the first planetary nebula discovered in the Phoenix dwarf galaxy
Ivo Saviane, Katrina Exter, Yiannis Tsamis +2
Context: A planetary nebula (PN) candidate was discovered during FORS imaging of the Local Group dwarf galaxy Phoenix. Aims: Use this PN to complement abundances from red-giant sta…
Decoding the spectra of SDSS early-type galaxies: New indicators of age and recent star formation
Ben Rogers, Ignacio Ferreras, Ofer Lahav +3
(Abridged) We apply Principal Component Analysis (PCA) to a sample of early-type galaxies from the Sloan Digital Sky Survey (SDSS) in order to infer differences in their star forma…
Using VO tools to investigate distant radio starbursts hosting obscured AGN in the HDF(N) region
A. M. S. Richards, T. W. B. Muxlow, R. Beswick +17
A 10-arcmin field around the HDF(N) contains 92 radio sources >40 uJy, resolved by MERLIN+VLA at 0".2-2".0 resolution. 55 have Chandra X-ray counterparts including 18 with a hard X…
First season QUaD CMB temperature and polarization power spectra
QUaD Collaboration, P. Ade, J. Bock +27
QUaD is a bolometric CMB polarimeter sited at the South Pole, operating at frequencies of 100 and 150 GHz. In this paper we report preliminary results from the first season of oper…
Principal Component Analysis as a tool to explore star formation histories
I. Ferreras, B. Rogers, O. Lahav +1
Principal Component Analysis (PCA) is a well-known multivariate technique used to decorrelate a set of vectors. PCA has been extensively applied in the past to the classification o…
The luminosity function of young star clusters: implications for the maximum mass and luminosity of clusters
Mark Gieles, Soeren Larsen, Nate Bastian +1
We introduce a method to relate a possible truncation of the star cluster mass function at the high mass end to the shape of the cluster luminosity function (LF). We compare the ob…
