High Frequency VLBI Rotation Measure of 8 AGN
J. C. Algaba
We have studied Very Long Baseline Array (VLBA) polarimetric observations of 8 sources including quasars and BL Lacs at 12, 15, 22, 24 and 43 GHz and high frequency rotation measur…
Jet Launching Structure Resolved Near the Supermassive Black Hole in M87
Sheperd S. Doeleman, Vincent L. Fish, David E. Schenck +30
Approximately 10% of active galactic nuclei exhibit relativistic jets, which are powered by accretion of matter onto super massive black holes. While the measured width profiles of…
Evolution of Post-Impact Companion Stars in SN Ia Remnants within the Single-Degenerate Scenario
Kuo-Chuan Pan, Paul Ricker, Ronald Taam
The nature of the progenitor systems of Type Ia supernovae is still uncertain. One way to distinguish between the single-degenerate scenario (SDS) and double-degenerate scenario (D…
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…
Launching and Quenching of Black Hole Relativistic Jets at Low Accretion Rate
Hung-Yi Pu, Kouichi Hirotani, Hsiang-Kuang Chang
Relativistic jets are launched from black hole (BH) X-ray binaries and active galactic nuclei when the disk accretion rate is below a certain limit (i.e., when the ratio of the acc…
Possible Detection of Apparent Superluminal inward motion in Markarian 421 after the Giant X-ray flare in February, 2010
K. Niinuma, M. Kino, H. Nagai +7
We report on the VLBI follow-up observations using the Japanese VLBI Network (JVN) array at 22 GHz for the largest X-ray flare of TeV blazar Mrk 421 that occurred in mid-February,…
Common Envelope Evolution: Where we stand and how we can move forward
N. Ivanova, S. Justham, X. Chen +16
This work aims to present our current best physical understanding of common-envelope evolution (CEE). We highlight areas of consensus and disagreement, and stress ideas which shoul…
Resolving the inner jet structure of 1924-292 with the EVENT HORIZON TELESCOPE
Ru-Sen Lu, Vincent L. Fish, Jonathan Weintroub +19
We present the first 1.3 mm (230 GHz) very long baseline interferometry model image of an AGN jet using closure phase techniques with a four-element array. The model image of the q…
Identifying the Location in the Host Galaxy of the Short GRB 111117A with the Chandra Sub-arcsecond Position
T. Sakamoto, E. Troja, K. Aoki +31
We present our successful Chandra program designed to identify, with sub-arcsecond accuracy, the X-ray afterglow of the short GRB 111117A, which was discovered by Swift and Fermi.…
VLBI and Single Dish Monitoring of 3C84 in the Period of 2009-2011
Hiroshi Nagai, Monica Orienti, Motoki Kino +13
The radio galaxy 3C 84 is a representative of gamma-ray-bright misaligned active galactic nuclei (AGNs) and one of the best laboratories to study the radio properties of the sub-pc…
Impact of type ia supernova ejecta on binary companions in the single-degenerate scenario
Kuo-Chuan Pan, Paul Ricker, Ronald Taam
Type Ia supernovae are thought to be caused by thermonuclear explosions of a carbon-oxygen white dwarf in close binary systems. In the single-degenerate scenario (SDS), the compani…
Energetic Fermi/LAT GRB100414A: Energetic and Correlations
Yuji Urata, Kuiyun Huang, Kazutaka Yamaoka +2
This study presents multi-wavelength observational results for energetic GRB100414A with GeV photons. The prompt spectral fitting using Suzaku/WAM data yielded spectral peak energi…
The GRB 071112C: A Case Study of Different Mechanisms in X-ray and Optical Temporal Evolution
K. Y. Huang, Y. Urata, Y. H. Tung +19
We present the study on GRB 071112C X-ray and optical light curves. In these two wavelength ranges, we have found different temporal properties. The R-band light curve showed an in…
