galaxies: interactionsgalaxies: star clusters: generalThe ACS and NICMOS have been used to obtain new HST images of NGC 4038/4039 ("The Antennae"). These new observations allow us to better differentiate compact star clusters from individual stars, based on both size and color. We use this ...
galaxies: ISMgalaxies: starburstgalaxies: star clusters: generalSuper star clusters --- extremely massive clusters found predominately instarburst environments --- are essential building blocks in the formation ofgalaxies and thought to dominate star formation in the high-redshift universe.However, the...
We compare mid-infrared images of the Antennae galaxies (NGC 4038/39) from the Infrared Space Observatory, with optical images from the Hubble Space Telescope. The midinfrared observations show that the most intense starburst in this colliding system of galaxies takes place in an off-nucleus regio...
Chandra Observations of "The Antennae" Galaxies (NGC 4038/4039). II. Detection and Analysis of Galaxian X-Ray Sources We report the detailed analysis of the X-ray properties of the discrete sources detected in a long (72 ks) Chandra ACIS-S observation of the Antennae galax... A Zezas,G...
We determine the mass function of young star clusters in the merging galaxies the ``Antennae'' (NGC 4038/39) from deep images taken with the WFPC2 on the refurbished Hubble Space Telescope (HST). This is accomplished by means of reddening-free parameters and a comparison with stellar populati...
of non-interacting galaxies. In the literature multiple gaus- sian have been used to approximate optical emission lines (Vanzi et al. 2002; Colina, Lipari & Macchetto 1991). In- terpretating the results of multi-gaussian fits in a physically ...
We calculate the Type Ia supernova (SN) rate for different star formation histories in galaxies by adopting the most popular and recent progenitor models. ... F Matteucci,S Recchi - 《Astrophysical Journal》 被引量: 194发表: 2001年 Chandra Observations of "The Antennae" Galaxies (NGC 4038/40...
Chandra Observations of "The Antennae" Galaxies (NGC 4038/4039). IV. The X-Ray Source Luminosity Function and the Nature of Ultraluminous X-Ray Sources We derive the X-ray luminosity function (XLF) of the X-ray source population detected in the Chandra observation of NGC 4038/4039 (the An...
