Subject: [tennet:2816] BH_workshop_2003
Dear colleagues,
We are organizing a workshop:
-----------------------------------------------------------------
Stellar-Mass, Intermediate-Mass, and Supermassive Black Holes
Kyoto International Community House, Kyoto, Japan
October 28 - 31, 2003
-----------------------------------------------------------------
It is based on a Grant-in-aid (Fiscal Year 2002-2006) for one of "Priority
Research Areas" in Japan; "New Development in Black Hole Astronomy." We have
deliberately chosen this period of the year, when Kyoto,the famous Old Capital
of Japan, assumes its highest autumn beauty. We would be very much delighted
if you could join us. Please inform your colleagues about this workshop.
----------
Objectives
----------
Black holes (BHs) are no longer purely imaginative or speculative concept,
but are real, observable objects. In this sense we can say that black-hole
research has entered a new era called black-hole astronomy.
Historically, astrophysical BHs were classified into two categories: stellar-
mass BHs found mostly in Our Galaxy, and supermassive ones in the center of
a certain class of distant galaxies. However, such a classical view has been
drastically renewed over the past decade, thanks to the rapid progress in
multi-wavelength observations as well as in theory and computation. Radio
and optical investigations have revealed that supermassive BHs are rather
ubiquitous (including our own Galactic Center), possibly in co-evolution with
their host galaxies. New aspects of Galactic BH transients under high accretion
rates have been obtained through multi-band studies, including X-ray coverage
with ASCA, BeppoSAX, and RXTE. Observations with ASCA, ROSAT, Chandra, and
XMM-Newton have revealed that intermediate-mass BHs may exist in nearby
galaxies, in the form of bright, compact, off-nuclear X-ray sources called
ultra-luminous X-ray sources (ULXs): an extreme case is the nearby starburst
galaxy M82, which may host an intermediate mass BH of about 1000 Solar mass.
Narrow-line Seyfert 1 galaxies (NLS1s) are another interesting subject, since
they seem to represent the lowest-mass end of the overall distribution of
supermassive BHs. Recent X-ray observations have revealed new and exciting
spectral complexities in these objects, of which the physical interpretation
is still under debate. Further, we have heard about the discovery of BHs in
the center of some globular clusters, though still controversial.
These discoveries suggest that there is a smooth BH mass distribution from
stellar-mass BHs through intermediate-mass objects up to supermassive ones,
even though we have a consensus on the formation scenario only for the
stellar-mass ones.
We believe it timely and meaningful to organize a workshop, to overview current
observations of BHs with different mass ranges, and construct a unified picture
on the physics underlying various phenomena which they manifest. The discussion
will naturally cover related theoretical issues of outstanding importance, such
as MHD accretion flows and disk-jet connection. In order to explore our
prospect, also important is new technology for future BH observations.
------------
Main topics
------------
Among various aspects of BHs under a rapid recent progress, we may focus on
the following topics with close mutual relation:
- Galactic BHs shining at Eddington luminosity
- Nature of ultra-luminous X-ray sources (ULXs)
- Narrow-line Seyfert 1 galaxies; a mile-stone
- Case of the Galactic center
- BH variability; multi-wavelength observations vs. theory
- Magnetohydrodynamical (MHD) accretion flow and jets
- Possible formation scenarios of the more massive BHs
- Observability of general relativistic effects
- New instrumentation for future BH research
-------------
Workshop plan
-------------
We will assign a quarter-day to a full-day session for each subject listed
above, each consisting of 2-4 invited talks as well as 4-10 contributed talks.
We will also have a poster session and ample time for poster discussion.
We may include selected reviews on those subjects which are not listed above,
but are sufficiently relevant, such as:
- Stellar- and gas-dynamical studies of supermassive BHs
- Co-evolution of galactic bulge and its central BH
- Gamma-ray bursts: optical afterglows and hypernova connection
- Particle acceleration
The number of participants will be limited to about 150 in order to facilitate
intensive discussion.

Hotels
------
We have booked 35 single rooms in Kyoto Royal Hotels for participants from
abroad during the conference periods. Kyoto Royal Hotel is located in
the downtown Kyoto and is about 30 minutes from the conference site by
using subway. The cost is about 10,000 yen per night (including breakfast).
If you wish to stay in this hotel, please send an email to
Ms. Noriko Komatsu (noriko@yukawa.kyoto-u.ac.jp)
We wish to ask participants from Japan to reserve hotel rooms individually.
There are plenty of hotels in Kyoto. The following is a list of nearby
hotels with reasonable costs. For reservation, please contact the hotels
directly. Note that autumn is very busy season in Kyoto. Better to book
as soon as possible.
