Discovery of a Highly Variable Dipping Ultraluminous X-ray source in M94
Dacheng Lin, Jimmy A. Irwin, Natalie A. Webb +2
We report the discovery of a new ultraluminous X-ray source (ULX) 2XMM J125048.6+410743 within the spiral galaxy M94. The source has been observed by ROSAT, Chandra, and XMM-Newton…
A ~3.8 hour Periodicity from an Ultrasoft Active Galactic Nucleus Candidate
Dacheng Lin, Jimmy A. Irwin, Olivier Godet +2
Very few galactic nuclei are found to show significant X-ray quasi-periodic oscillations (QPOs). After carefully modeling the noise continuum, we find that the ~3.8 hr QPO in the u…
Classification of X-ray Sources in the XMM-Newton Serendipitous Source Catalog: Objects of Special Interest
Dacheng Lin, Natalie A. Webb, Didier Barret
We analyze 18 sources that were found to show interesting properties of periodicity, very soft spectra and/or large long-term variability in X-rays in our project of classification…
XMM-Newton Observations of the TeV γ-ray Source HESS J1804-216
Dacheng Lin, Natalie A. Webb, Didier Barret
We have analyzed three XMM-Newton observations of the central part of the unidentified TeV γ-ray source HESS J1804-216. We focus on two X-ray sources 2XMMi J180442.0-214221 (Src 1)…
