Multiwavelength Study of Dark Globule DC 314.8-5.1: Point Source Identification and Diffuse Emission Characterization
E. Kosmaczewski, L. Stawarz, C. C. Cheung +3
We present an analysis of multi-wavelength observations of the dark globule DC\,314.8--5.1, using data from the Gaia optical, 2MASS near-infrared, and WISE mid-infrared surveys, de…
Discovery of Candidate X-ray Jets in High-Redshift Quasars
Bradford Snios, Daniel A. Schwartz, Aneta Siemiginowska +8
We present Chandra X-ray observations of 14 radio-loud quasars at redshifts , selected from a well-defined sample. All quasars are detected in the 0.5-7.0 keV energy ban…
Two Candidate High-Redshift X-ray Jets Without Coincident Radio Jets
Daniel Schwartz, Aneta Siemiginowska, Brad Snios +7
We report the detection of extended X-ray emission from two high-redshift radio quasars. These quasars, J1405+0415 at =3.208 and J1610+1811 at =3.118, were observed in a Chan…
X-ray Properties of Young Radio Quasars at z > 4.5
Bradford Snios, Aneta Siemiginowska, Małgosia Sobolewska +6
We present a comprehensive analysis of Chandra X-ray observations of 15 young radio quasars at redshifts . All sources are detected in the keV energy band.…
Chandra Imaging of the Western Hotspot in the Radio Galaxy Pictor A: Image Deconvolution and Variability Analysis
R. Thimmappa, Ł. Stawarz, V. Marchenko +3
Here we present an analysis of the X-ray morphology and flux variability of the particularly bright and extended Western hotspot in the nearest powerful (FR II-type) radio galaxy,…
Mid-Infrared Diagnostics of the Circumnuclear Environments of the Youngest Radio Galaxies
E. Kosmaczewski, L. Stawarz, A. Siemiginowska +6
We present a systematic analysis of the mid-infrared (MIR) properties of the youngest radio galaxies, based on low-resolution data provided by the {\it WISE} and {\it IRAS} satelli…
