| Abstract : | FUV and NUV observations have the advantage of tracing older and less massive stars (≤
200 Myr, O to early B type) compared to Hα (≤ 10 Myr, early to mid-O type stars). The
UVIT and MUSE are among the best instruments to study star forming complexes (SFCs)
in UV and Hα emission due to their high angular resolution of ≈1.2” and ≈ 0.9”. In this
poster, we will present preliminary results on the correlation between the UV (FUV and
NUV) and Hα luminosities and star formation rates for the SFCs in the inner disk of NGC
628 using UVIT and MUSE data. We also compare the number of star forming complexes in
all three bands (MUSE convolved to UVIT resolution). Our preliminary study shows that
there are relatively more Hα complexes than expected than those detected in FUV
and NUV. Also, FUV and NUV-emitting SFCs are mainly found in spiral arms, whereas Hα
complexes are present in the arm and interarm regions. We show how the Muse IFU data and
the stellar population models can be used to derive some SFC properties, from which we can
get a better age estimation of the SFCs. |
