A review of the published LFs for the globular cluster (GC) M92 suggests that the morphology of the transition from the main sequence to the red giant branch (ltGB) is sensitive to these parameters. In particular, a small bump in this region may provide an important age discriminant for GCs. A significant deficiency in the number of stars over a 2 mag interval, just below the turnoff, remains unexplained. -

We use 3D numerical simulations to study the evolution of the Hα intensity and velocity dispersion for single and multiple supernova (SN) explosions. We find that the IHα{ σ diagram obtained for simulated gas flows is similar in shape to that observed in dwarf galaxies. We conclude that collid- ing SN shells with significant difference in age are responsible for high velocity dispersion that reaches up to ∼> 100 km s−1. Such a high velocity dispersion could be hardly obtained for a single SN remnant. Peaks of velocity disper- sion in the IHα{ σ diagram may correspond to several isolated or merged SN remnants with moderately different ages. Degrading the spatial resolution in the Hα intensity and velocity dispersion maps makes the simulated IHα{ σ di- agrams close to those observed in dwarf galaxies not only in shape, but also quantitatively.

Extra-Nuclear Starbursts: Young Luminous Hinge Clumps In
Extra-Nuclear Starbursts: Young Luminous Hinge Clumps in Interacting Galaxies Beverly J. Smith1, Roberto Soria2, Curtis Struck3, Mark L. Giroux1, Douglas A. Swartz4, and Mihoko Yukita5 ABSTRACT Hinge clumps are luminous knots of star formation near the base of tidal features in some interacting galaxies. We use archival Hubble Space Telescope UV/optical/IR images and Chandra X-ray maps along with GALEX UV, Spitzer IR, and ground-based optical/near-IR images to investigate the star forming properties in a sample of 12 hinge clumps in five interacting galaxies. 1 The most extreme of these hinge clumps have star formation rates of 1 9 M yr− , comparable to or larger than the ‘overlap’ region of intense star formation between− the⊙ two disks of the colliding galaxy system the Antennae. In the HST images, we have found remarkably large and luminous sources at the centers of these hinge clumps. These objects are much larger and more luminous than typical ‘super-star clusters’ in interacting galaxies, and are sometimes embedded in a linear ridge of fainter star clusters, consistent with star formation along a narrow caustic. These central sources have diameters of 70 pc, compared to 3 pc in ‘ordinary’ super-star clusters. ∼ ∼ Their absolute I magnitudes range from MI 12.2 to 16.5, thus if they are individual star clusters they would lie near the top of the ‘super∼ − star cluster’− luminosity function of star clusters. These sources may not be individual star clusters, but instead may be tightly packed groups of clusters that are blended together in the HST images. -

The X-Ray Luminosity Function of Ultra Luminous X-Ray Sources in Collisional Ring Galaxies
Draft version June 8, 2018 Typeset using LATEX twocolumn style in AASTeX62 The X-Ray Luminosity Function of Ultra Luminous X-Ray Sources in Collisional Ring Galaxies Anna Wolter,1 Antonella Fruscione,2 and Michela Mapelli3 1INAF-Osservatorio Astronomico di Brera, via Brera 28, 20121 Milano, Italy 2Harvard-Smithsonian Center for Astrophysics, 60 Garden St., Cambdidge, MA, 02138 3INAF-Osservatorio Astronomico di Padova, vicolo dell'Osservatorio 5, 35122, Padova, Italy (Received March, 7th, 2018; Accepted June, 5th, 2018) Submitted to The Astrophysical Journal ABSTRACT Ring galaxies are fascinating laboratories: a catastrophic impact between two galaxies (one not much smaller than the other) has produced fireworks especially in the larger one, when hit roughly perpendicularly to the plane. We analyze the point sources, produced by the starburst episode following the impact, in the rings of seven galaxies and determine their X-ray luminosity function (XLF). In 39 −1 total we detect 63 sources, of which 50 have luminosity LX ≥ 10 erg s , classifying them as ultra luminous X-ray sources (ULXs). We find that the total XLF is not significantly different from XLFs derived for other kinds of galaxies, with a tendency of having a larger fraction of high X-ray luminosity objects. Both the total number of ULXs and the number of ULXs per unit star formation rate are found in the upper envelope of the more normal galaxies distribution. Further analysis would be needed to address the issue of the nature of the compact component in the binary system. Keywords: galaxies: individual (AM0644-741, Arp143, Arp148) - galaxies: peculiar - galaxies: star formation - X-ray binaries 1. -
A Formation Mechanism of the Clumpy Irregular Galaxy
WING GALAXIES: A FORMATION MECHANISM OF THE CLUMPY IRREGULAR GALAXY MARKARIAN 297 YOSHIAKITANIGUCHI Kiso Observatory, Institute of Astronomy, The University of Tokyo MASAFUMINOGUCHI Department of Physics, University of wales In order to cbnhibute to an understanding of collision-induced starburst activities, we r present a detailed case study on the starburst galaxy Markarian 297 (= NGC 6052 = Arp 209; hereafter Mrk 297). This galaxy is classified as a clumpy irregular galaxy (hereafter CIGs) according to its morphological properties (cf. Heidmann, 1987). Two major clumps and many small clumps are observed in the entire region of Mrk 297 (Hecquet, Coupinot, and Maucherat 1987). A typical major clump of CIGs has a diameter of a few hundred pc and its dynamical mass is estimated as an order of 108 Ma (Taniguchi and Tmwa 1987). Since Mrk 297 looks like an isolated system, Schweizer (1983) included it as a candidate of mergers. On the other hand, Alloin and Duflot (1979) proposed another idea that Mrk 297 is just a colliding system betweeri 'two late-type spiral galaxies because this galaxy has two kinematically distinct components '(the two major clumps). Following their suggestion, we try to consider a possible geometry and. orbit of the interaction in Mrk 297. ~I The overall morphology of Mrk 297 is highly chaotic and thus it seems difficult to determine possible orbits of galaxy-galaxy collision. However, we have serendipit ously found a possible orbit during a course of numerical simulations for a radial-penetration collision between galaxies. The radial-penetration collision means that an intruder penetrates a target galaxy radially passing by its nucleus. -

Based on a large sample of disk and halo giant stars for which accurate effective temperatures derived through the InfraRed Flux Method (IRFM) exist, a calibration of the temperature scale in the Vilnius, Geneva, RI(C) and DDO photometric systems is performed. We provide calibration formulae for the metallicity-dependent Teff vs. color relations as well as grids of intrinsic colors and compare them with other calibrations. Photometry, atmospheric parameters and reddening corrections for the stars of the sample have been updated with respect to the original sources to reduce the dispersion of the fits. Application of our results to Arcturus leads to an effective temperature in excellent agreement with the value derived from its angular diameter and integrated flux. The effects of gravity on these Teff vs. color relations are also explored by taking into account our previous results for dwarf stars. Key words. -
