Origin of the double-peaked narrow emission-lines in the optical spectra of X-shaped Radio Galaxies
Ghosh Prajnadipt, Ravi Joshi, Xiaolong Yang +13
We investigate X-shaped radio galaxies (XRGs) with optical double-peaked narrow emission lines (DPNELs) as potential hosts of dual or binary supermassive black holes (SMBHs). Using…
The absence of radio emission from the globular cluster G1
J. C. A. Miller-Jones, J. M. Wrobel, G. R. Sivakoff +9
The detections of both X-ray and radio emission from the cluster G1 in M31 have provided strong support for existing dynamical evidence for an intermediate mass black hole (IMBH) o…
The application of slim disk models to ULX: the case of M33 X-8
L. Foschini, K. Ebisawa, T. Kawaguchi +8
A comparative XMM-Newton archival data spectral study of the ultraluminous X-ray source (ULX) M33 X-8 has been performed by using both the standard disk model and the newly develop…
Masses of star clusters in the nuclei of bulge-less spiral galaxies
C. J. Walcher, R. P. van der Marel, D. McLaughlin +6
In the last decade star clusters have been found in the centers of spiral galaxies across all Hubble types. We here present a spectroscopic study of the exceptionally bright (10^6…
Testing Radiatively-Inefficient Accretion Flow Theory: an XMM-Newton Observation of NGC 3998
A. Ptak, Y. Terashima, L. C. Ho +1
We present the results of a 10 ks XMM-Newton observation of NGC 3998, a ``type-I'' LINER galaxy. Our goal is to test the extent to which radiatively-inefficient accretion flow (RIA…
Yet another galaxy identification for an ultraluminous X-ray source
N. Masetti, L. Foschini, L. C. Ho +4
We report on the identification of the optical and infrared counterparts of the ultraluminous X-ray source (ULX) XMMU J121214.5+131248 (NGC4168-ULX1). The optical spectrum yields a…
