Subject: JEM-X Monday Meeting 2007-06-04

Participants: SB, CBJ, EK (Emrah Kalemci), NL, JC, CAO, NJW.

Welcome of Emrah Kalemci who will be visiting DNSC for the month
of June 2007, starting now.

JEM-X status (SB): Smooth running. Hotspot activity is very low.

Status of OSA deliveries (CAO, NL, NJW, JC): j_cor_position has
been delivered with the option of randomized (within the pixel)
positions.
With the software freeze for OSA7 being postponed to end of July
we should aim at make a delivery of j_ima_iros with the improvements
that are working now in the test version.
j_ima_cross and j_ima_mosaic will not be (re)delivered for OSA7.

AX J1754.2-2754 burst (ATEL #1094 by Chelovekov) was discussed.
GX5-1 was in the JEM-X FOV (Rev 306, PID 50).

EDGE project (CBJ, returning from workshop): Wide field monitor,
autonomous turn of satellite to study afterglow with high energy
resolution instrument (a few eV).  Wide field X-ray telescope.
A meeting between us and Luigi Piro and Jean-Willem den Herder
is planned to take place e.g. June 21 (2007).
Has dark matter something to do with 'sterile neutrinos'?

Multicolor workshop at Volcano Island (NL): TeV astronomy is
taking up speed now 'Magic', 'Kangaroo' Cherenkov telescopes
have improved direction determinations and 80 sources in the
kev range are known now.
There are some doubts about the shock acceleration of cosmic
ray particles.
Very close binary (normal) stars appear not seldomly in the
INTEGRAL source catalog - you don't necessarily need a compact
object to produce high energy radiation.
RRATs (Rotating Radio Transients) in radio astronomy
- single pulse emitters with quite high intensity followed by
a idle time of many periods.
Chandra and XMM-Newton are now following up on this and X-ray
counterparts have been seen as X-ray pulsars.
