“…In this study, our possible four SNR candidates (see Table 4) are all found to be in a good agreement with their 20 cm radio locations. Our H ii regions reported here are consistent with the findings of Vucetić et al [65] results.

The results of an optical search for supernova remnants (SNRs) in the nearby irregular galaxy NGC 2366 are presented. We took interference filter images and collected spectral data in three epochs with the f/7.7 1.5 m Russian Turkish Telescope (RTT150) at T ÜB İTAK National Observatory (TUG) located in Antalya, Turkey. The continuum-subtracted Hα and continuum-subtracted [S ii]λλ6716, 6731 images and their ratios were used for the identification of SNRs. With [S ii]/Hα ≥ 0.4 criteria, four possible SNR candidates were identified in NGC 2366 with [S ii]/Hα ratios of ∼(0.68, 0.57, 0.55 and 0.75), Hα intensities of ∼(2.10, 0.36, 0.14, 0.11)×10 −15 erg cm −2 s −1 [S ii]λ6716/λ6731 average flux ratios of ∼(1.01 and 1.04), electron densities of N e ∼(582 and 513) cm −3 and [O iii] λ5007/Hβ λ4861 ∼(3.6 and 2.6) line ratio values are obtained for two of the SNR candidates. A shock velocity V s of 80 ≤ V s ≤ 100 km s −1is reported. The spectral parameters are obtained for the first time for these possible SNR candidates. The locations of the four SNRs obtained here are found to be consistent with optical and radio results reported so far. One of the sources categorised earlier by XMM-Newton observations as an extended X-ray source position is found to be consistent with one of four possible SNR $ Fully documented templates are available in the elsarticle package on CTAN.

Investigations of blue compact galaxies (BCGs) are essential to advancing our understanding of galaxy formation and evolution. BCGs are low-luminosity, low-metallicity, gas-rich objects that form stars at extremely high rates, meaning they are good analogs to the high-redshift star-forming galaxy population. Being low-mass starburst systems, they also constitute excellent laboratories in which to investigate the star formation process and the interplay between massive stars and their surroundings. This work presents results from integral field spectroscopic observations of the BCG Haro 14 taken with the Multi Unit Spectroscopic Explorer (MUSE) at the Very Large Telescope in wide-field adaptive optics mode. The large MUSE field of view (1 ′ × 1 ′ =3.8 × 3.8 kpc 2 at the adopted distance of 13 Mpc) enables simultaneous observations of the central starburst and the low-surface-brightness host galaxy, which is a huge improvement with respect to previous integral field spectroscopy of BCGs. From these data we built galaxy maps in continuum and in the brightest emission lines. We also generated synthetic broad-band images in the VRI bands, from which we produced color index maps and surface brightness profiles. We detected numerous clumps spread throughout the galaxy, both in continuum and in emission lines, and produced a catalog with their position, size, and photometry. This analysis allowed us to study the morphology and stellar populations of Haro 14 in detail. The stellar distribution shows a pronounced asymmetry; the intensity peak in continuum is not centered with respect to the underlying stellar host but is displaced by about 500 pc southwest. At the position of the continuum peak we find a bright stellar cluster that with M v = −12.18 appears as a strong super stellar cluster candidate. We also find a highly asymmetric, blue, but nonionizing stellar component that occupies almost the whole eastern part of the galaxy. We conclude that there are at least three different stellar populations in Haro 14: the current starburst of about 6 Myr; an intermediate-age component of between ten and several hundred million years; and a red and regular host of several gigayears. The pronounced lopsidedness in the continuum and also in the color maps, and the presence of numerous stellar clusters, are consistent with a scenario of mergers or interactions acting in Haro 14.
