The quasar PG 0844+349 in an X-ray weak state
L. C. Gallo, D. Grupe, N. Schartel +4
In March 2009 the well-studied quasar, PG 0844+349, was discovered with Swift to be in an X-ray weak state. A follow-up XMM-Newton observation several weeks later generated a good…
Multi-epoch X-ray observations of the Seyfert 1.2 galaxy Mrk 79: bulk motion of the illuminating X-ray source
L. C. Gallo, G. Miniutti, J. M. Miller +4
Multi-epoch X-ray spectroscopy (0.3-25 keV) of the Seyfert 1.2 galaxy Mrk 79 (UGC 3973) spanning nearly eight years and a factor of three in broadband flux are analysed. The data a…
Herschel observations of FIR emission lines in brightest cluster galaxies
A. C. Edge, J. B. R. Oonk, R. Mittal +24
The question of how much gas cools in the cores of clusters of galaxies has been the focus of many, multiwavelength studies in the past 30 years. In this letter we present the firs…
Star Formation in the Outer Filaments of NGC 1275
R. E. A. Canning, A. C. Fabian, R. M. Johnstone +5
We present photometry of the outer star clusters in NGC 1275, the brightest galaxy in the Perseus cluster. The observations were taken using the Hubble Space Telescope Advanced Cam…
