12 月 12 日 | 佐藤 |
In the next seminar (12th Dec.), I would like to talk about the power
spectrum density (PSD) of AGN. PSD analysis is major method to
investigate the variability of AGN. I will introduce a review paper and
recent researches.

In the next seminar (19th Dec.), I would like to introduce
the observational study of peculiar SNe Ia. This class is
known to deviate from the width-luminosity relation of
Type Ia SNe.
I first introduce the following paper: "TYPE Iax SUPERNOVAE: A NEW CLASS OF STELLAR EXPLOSION" Foley et al., 2012, ArXiv e-prints, 1212.2209v1 Then, I may report the our observational results of another object observed by OISTER. |

The title of my talk in this Wednesday will be:
``Gamma-ray emission from galaxies'' The talk will be based on -Ackermann et al.(2012), ApJ, 755, 164 "GeV Observations of Star-forming Galaxies with the Fermi Large Area Telescope" -Ackermann et al.(2012), ApJ, 747, 104 "Search for Gamma-ray Emission from X-Ray-selected Seyfert Galaxies with Fermi-LAT" Also, I will include some general introductions of the cosmic-ray and gamma-ray physics. |
2 月 6 日 | Ricci |
The title of my talk this Wednesday will be:
"Probing the evolution of Active Galactic Nuclei using the Iron Kalpha" line I will first review the recent developments in our understanding of the unification of Active Galactic Nuclei (AGN), and then present you some recent work I have been doing on this subject. My talk will be mostly based on recent X-ray and IR studies of AGN, with a particular attention to the features generated by reflection of the X-ray emission by circumnuclear material, and to their evolution. I will also shortly discuss how much the advent of the new generation X-ray telescope ASTRO-H will improve our understanding of AGN. Some of the papers I will present you on this fascinating subject are Shu et al. (2010) http://adsabs.harvard.edu/abs/2010ApJS..187..581S Shu et al. (2011) http://adsabs.harvard.edu/abs/2011ApJ...738..147S Shu et al. (2012) http://adsabs.harvard.edu/abs/2012ApJ...744L..21S Burlon et al.

I would like to reports our work and review the following paper:
"FITTING LINER NUCLEI WITHIN AGN FAMILY: A MATTER OF OBSCURATION ?"
The Astrophysical Journal, Volume 704, Issue 2, pp. 1570-1585 (2009).
This paper reports the studies of the nuclear obscuration in LINERs and the raletion between the LINERs and the other types of AGN. |
2 月 27 日 | 笹田 |
I will talk about an analysis of time variation of a blazar.
A title of my presentation is
"Time Variability Analysis of Blazars". My presentation is based on these papers; "GAMMA-RAY LIGHT CURVES AND VARIABILITY OF BRIGHTFERMI-DETECTED BLAZARS" Abdo et al.
