Bidimensional spectroscopy of NGC 4214 : evolutionary state and interstellar extinction
We have mapped spectrophotometrically the star– forming regions in the center of the nearby SBm galaxy NGC 4214 with the aim of analyzing the spatial distribution of some of its physical properties (density, excitation, emission line intensity, extinction) and their relationshipwith the distribution and evolutionary state of the stellar population. Star formation takes place mainly in two big c...
متن کاملDiscovery of a 3.6-hr Eclipsing Luminous X-ray Binary in the Galaxy Ngc 4214
We report the discovery of an eclipsing X-ray binary with a 3.62-hr period within 24 of the center of the dwarf starburst galaxy NGC 4214. The orbital period places interesting constraints on the nature of the binary, and allows for a few very different interpretations. The most likely possibility is that the source lies within NGC 4214 and has an X-ray luminosity, Lx, of up to 7 × 10 ergs s. I...
متن کاملTip of the Red Giant Branch Distances to NGC 4214 , UGC 685 , and UGC 5456 1
We have used WFPC2 V RI observations to calculate the distances to three nearby galaxies, NGC 4214, UGC 685, and UGC 5456 using the tip of the red giant branch method. Our values for NGC 4214 (2.94 ± 0.18 Mpc) and UGC 685 (4.79 ± 0.30 Mpc) are the most precise measurementes of the distances to these objects ever made. For UGC 5456 the data do not allow us to reach a decisive conclusion since th...
متن کامل3D Studies of Neutral and Ionised Gas and Stars in Seyfert and Inactive Galaxies
We are conducting the first systematic 3D spectroscopic imaging survey to quantify the properties of the atomic gas (Hi) in a distance-limited sample of 28 Seyfert galaxies and a sample of 28 inactive control galaxies with well-matched optical properties (the VHIKINGS survey). This study aims to address the role of the host galaxy in nuclear activity and confront outstanding controversies in op...
متن کاملNeutral hydrogen in galactic fountains
Simulations of an isolated Milky Way-like galaxy, in which supernovae power a galactic fountain, reproduce the observed velocity and 21 cm brightness statistics of galactic neutral hydrogen (H i). The simulated galaxy consists of a thin H i disk, similar in extent and brightness to that observed in the Milky Way, and extra-planar neutral gas at a range of velocities due to the galactic fountain...
