Multi-wavelength outburst activity from EP J174942.2-384834: a very faint X-ray transient discovered by Einstein Probe
F. Coti Zelati, A. Marino, Y. L. Wang +27
We report the discovery and multi-wavelength characterization of the Galactic transient EP J174942.2384834, first detected by the Einstein Probe during a faint X-ray outburst in…
Chandra and MMT observations of low-mass black hole active galactic nuclei accreting at low rates in dwarf galaxies
W. Yuan, H. Zhou, L. Dou +3
We report on Chandra X-ray observations of four candidate low-mass black hole (<10^6Msun) active galactic nuclei (AGNs) that have the estimated Eddington ratios among the lowest (~…
A comparative study of optical/ultraviolet variability of narrow-line Seyfert 1 and broad-line Seyfert 1 active galactic nuclei
Y. L. Ai, W. Yuan, H. Zhou +4
The ensemble optical/ultraviolet variability of narrow-line Seyfert 1 (NLS1) type active galactic nuclei (AGNs) is investigated, based on a sample selected from the Sloan Digital S…
Disk corona interaction: mechanism for the disk truncation and spectrum change in low luminosity AGN
Ronald E. Taam, B. F. Liu, W. Yuan +1
The truncation of an optically thick, geometrically thin accretion disk is investigated in the context of low luminosity AGN (LLAGN). We generalize the disk evaporation model used…
A Uniformly Selected Sample of Low-mass Black Holes in Seyfert 1 Galaxies
Xiao-Bo Dong, Luis C. Ho, Weimin Yuan +4
We have conducted a systematic search of low-mass black holes (BHs) in active galactic nuclei (AGNs) with broad Halpha emission lines, aiming at building a homogeneous sample that…
