The Structure of the Circumstellar Envelope of SN 1987A
Arlin P. S. Crotts
The volume around the SN 1987A contains a variety of structures, not just the three rings glowing in recombination lines. Many of these are revealed by light echoes, so are mapped…
MEGA, a Wide-Field Survey of Microlensing in M31
A. P. S. Crotts, R. Uglesich, G. Gyuk
We detail how microlensing internal to M31 could be used to test whether a large fraction of the matter in spiral galaxy haloes is composed of dark objects with masses comparable t…
ISO SWS/LWS observations of SN 1987A
P. Lundqvist, J. Sollerman, C. Kozma +5
We report on observations of SN 1987A with ISO SWS/LWS made 9 - 11 years after the explosion. No emission from the supernova was seen. In particular, the upper limits on the fluxes…
Expectations from Realistic Microlensing Models of M31. I: Optical Depth
Geza Gyuk, Arlin Crotts
We provide a set of microlensing optical depth maps for M31. Optical depths towards Andromeda were calculated on the basis of a four component model of the lens and source populati…
