Abstract:
We present results from Chandra observations of the X-ray starburst
galaxies NGC3310 and NGC2276. We detect 27 discrete sources in
NGC3310, and 19 discrete sources in NGC2276 with luminosities above
1.0x1038erg/s. The majority of the sources have photon indices of
1.7-2.0, typical for X-ray binaries. Both galaxies have large numbers
of ultra-luminous X-ray sources (ULXs; sources with
L(0.3-10.0keV)>1039erg/s), 14 for NGC3310 concentrated on the
circumnuclear star-forming ring and north spiral arm and 11 for
NGC2276 with the brighter ones on the west side of the galaxy which is
compressed due to harassment by the intra-group medium it is moving
into. We find for both galaxies that the ULX-hosting areas are located
above the general LX-SFR scaling relations while other areas either
follow or fall below the scaling relations. This indicates that
sub-galactic regions follow the galaxy-wide scaling relations but with
much larger scatter resulting from the age (and possibly metallicity)
of their local stellar populations in agreement with recent
theoretical and observational results. Such differences in age could
be the origin of the scatter we observe in the low-SFR regime in the
Lx-SFR scaling relations.
Description:
In this work, we use observations obtained with the ACIS-S camera
(Garmire 1997AAS...190.3404G 1997AAS...190.3404G) on board the Chandra X-ray observatory
(Weisskopf et al. 2000SPIE.4012....2W 2000SPIE.4012....2W) for the galaxies NGC 3310 and
NGC 2276. The observations for NGC 3310 were performed on January 15th
2003 (OBSID 2939; 47.16ks) and October 22nd 2016 (OBSID 19891;
35.84ks). A much shorter observation (10ks; OBSID 1602) performed on
the 11th of June 2014 is not included in our analysis since it will
complicate the analysis without improving the statistics. The
observations for NGC 2276 were performed on June 23rd 2004 (OBSID
4968; 45.57ks) and May 14th 2013 (OBSID 15648; 24.74ks).
