Smithsonian Astrophysical Observatory Memorandum To : From Date: Re: M. Cappi, Strong Gravity SDT/YB Team, XMS team : M. Garcia April 14, 2010 XMS high/mid/low resolution event rates for bright AGN mrg-2010-02v2 This memo arises out of the concern that the bright AGN that will be used to observed strong gravity effects ­ in particular those for which time-resolved measurements of test particle orbits will be made ­ may generate counting rates in the XMS that are sufficient to overwhelm it. ...

... Bad Astronomy . ... Site Info . ... As part of the SINS project, many images of supernova 1987A have been made with the Hubble Space Telescope. This is an image of the supernova and surrounding nebulosity. ... This image shows the ring in [OIII] fading over a three year period. ...

... The SN 1998bv discovered on April 6, 1998 in the blue compact galaxy HS 1035+4758 is the second supernova observed in a low-mass galaxy with intense SF burst. ... According to its characteristic spectrum, SN 1998bv is a type II supernova with estimated peak absolute brightness M 16.3. The very slow fading of its brightness suggests that the SN was discovered at the Plateau phase, 20-30 days after the peak of the light curve. The most probable classification of SN 1998bv is regular SN II-P. 3. ...
