Title: PROPOSAL TO STUDY THE HOT GAS INTERIOR OF A SUPERGIANT SHELL IN THE NEARBY DWARF GALAXY IC 2574
Observer: WALTER
Subject Category: Normal Galaxies
Seq: 600095 ObsId: 00792
Long-term Plan bin: 28-Dec-1999
ABSTRACT
We propose to observe a supergiant shell within the nearby (3.2 Mpc) dwarf galaxy IC 2574. It coincides with a cavity in HI and is surrounded by HII regions. The region is detected with IRAS, in the radio continuum, with the EINSTEIN satellite and with ROSAT. It is the most active star forming region in IC 2574. ROSAT PSPC data (60 counts) suggest that the cavity is filled with a hot plasma. An AXAF pointed observation with the ACIS-S-BI CCD chip S3 of 10 ksec integration time is requested to confirm the extended nature of the source, to determine its thermal spectrum to an accuracy of 10%, and to check for the contribution from unresolved sources.
