Discovery of a New Galactic Center Excess Consistent with Upscattered Starlight

Kevork N. Abazajian, Nicolas Canac, Shunsaku Horiuchi +2

We present a new extended gamma ray excess detected with the Fermi Satellite Large Area Telescope toward the Galactic Center that traces the morphology of infrared starlight emissi…

The red supergiant and supernova rate problems: implications for core-collapse supernova physics

Shunsaku Horiuchi, Ko Nakamura, Tomoya Takiwaki +2

Mapping supernovae to their progenitors is fundamental to understanding the collapse of massive stars. We investigate the red supergiant problem, which concerns why red supergiants…

Multiwavelength campaign on Mrk 509 XIV. Chandra HETGS spectra

J. S. Kaastra, J. Ebrero, N. Arav +14

We present in this paper the results of a 270 ks Chandra HETGS observation in the context of a large multiwavelength campaign on the Seyfert galaxy Mrk 509. The HETGS spectrum allo…

Weak Hard X-ray Emission from Broad Absorption Line Quasars: Evidence for Intrinsic X-ray Weakness

B. Luo, W. N. Brandt, D. M. Alexander +19

We report NuSTAR observations of a sample of six X-ray weak broad absorption line (BAL) quasars. These targets, at z=0.148-1.223, are among the optically brightest and most luminou…

A fast and long-lived outflow from the supermassive black hole in NGC 5548

J. S. Kaastra, G. A. Kriss, M. Cappi +31

Supermassive black holes in the nuclei of active galaxies expel large amounts of matter through powerful winds of ionized gas. The archetypal active galaxy NGC 5548 has been studie…

Multiwavelength campaign on Mrk 509. XIII. Testing ionized-reflection models on Mrk 509

R. Boissay, S. Paltani, G. Ponti +12

Active Galactic Nuclei (AGN) are the most luminous persistent objects in the universe. An excess of X-ray emission below about 2 keV, called soft-excess, is very common in Type 1 A…
