HEASOFT 6.15

(2014-04-03)
** Env.
- heasoft 6.15.1 source build
- Mac OS X 10.8
Darwin Kernel Version 12.5.0
- Xcode 5.1
- Homebrew 0.9.5

** (1)
configure: error: ar not found in your $PATH. See your sysdamin.
->
check Xcode
You need Command Line Tools installed in Xcode by
「Xcode->Preferences->Downloads」->「Command Line Tools」

** (2) x86_64 Fortran compiler detected...
checking whether gfortran accepts -m32... no
configure: error: This Fortran compiler is not supported for a 32-bit/i386 build.
I used gfortran from brew
GNU Fortran (GCC) 4.8.2

see
http://heasarc.nasa.gov/docs/software/lheasoft/support.html#Mac10.8

->
brew install gfortran --enable-multilib
(thanks to Sakai-kun)
and build heasoft again.
This solves the error.

My talk:
X-ray measurements of gas bulk motions in galaxy clusters

X-ray studies of velocity structures of the intracluster medium is one of the primary goals for future X-ray missions. High resolution spectroscopy will provide measurements of energy distributions not only in thermal but also in kinematic forms. These provide understanding of cluster formation and reductions of systematic uncertainties in cluster total masses for precise cosmology. Using Suzaku we have detected a motion of a sub component with a velocity of about 1500 km/s for the first time by X-ray of a X-ray bright merging cluster, Abell2256 (Tamura et al. 2011). We also detected a hint of bulk motion in the Perseus cluster core (Tamura et al. 2013). In addition we attempted to measure 'X-ray gas redshift' of clusters. We found that gas are moving in pair with galaxies at least in X-ray bright central regions. In addition to these new Suzaku results, future studies of gas bulk motion along with turbulent motions by X-ray micro calorimeter onboard ASTRO-H will be discussed.

(ISAS seminar) Speaker: Daniel Asmus (Max-Planck-Institut für Radioastronomie, MPIfR, Bonn, Germany) Title: The mid-infrared properties of local active galactic nuclei Abstract: The local active galactic nuclei (AGN) population enables us to study in detail the structures and radiation processes in the direct environment of the supermassive black holes in galaxy centers and to develop an understanding of the general AGN phenomenon. For this purpose, the first unbiased sample of 104 local AGN has now become available thanks to Swift/BAT observations in the hard X-ray regime. We performed high-angular resolution mid-infrared (MIR) imaging observations of most of these AGN with VLT/VISIR and Gemini/Michelle in order to study the dusty tori in these objects -- a key component in AGN models. At the same time, we obtained similar data of a complementary sample of AGN in the low-luminosity regime. I present the results of both programmes and show that unresolved MIR emission is present in the AGN of both samples, which is consistent with thermal emission from dust in the direct vicinity of the AGN. Furthermore, the MIR emission is strongly correlated with the absorption-corrected 2-10 keV X-ray emission over the whole range of luminosities (10^40 to 10^45 erg/s). These results agree with the standard unification model being valid for all types of

自分の体，
身の回りのいろいろな物，
地球，そして宇宙は何からできているのだろう？
この謎を，多くの人々が探求してきた。
これに答えるには，物理の法則と素粒子の成り立ちを理解する必要がある。
四つの力は統一できるのだろうか？
クオークやレプトンはそれ以上，分解できないだろうか？
究極の理論はどんな数学で記述できろだろうか？

この広大な宇宙も実はいくつかの素粒子で作られている。
