Hubble Gazes at Fluffy-Looking Galaxy 20 March 2020 Image: Hubble gazes at fluffy-looking galaxy 20 March 2020 hope to solve by studying galaxies in the nearby universe, such as NGC 4237. Provided by NASA's Goddard Space Flight Center Credit: ESA/Hubble & NASA, P. Erwin et al. This image taken by the NASA/ESA Hubble Space Telescope shows the galaxy NGC 4237. Located about 60 million light-years from Earth in the constellation of Coma Berenices (Berenice's Hair), NGC 4237 is classified as a flocculent spiral galaxy. This means that its spiral arms are not clearly distinguishable from each other, as in "grand design" spiral galaxies, but are instead patchy and discontinuous. This gives the galaxy a fluffy appearance, somewhat resembling fluffy cotton. Astronomers studying NGC 4237 were actually more interested in its galactic bulge—its bright central region. By learning more about these bulges, we can explore how spiral galaxies have evolved, and study the growth of the supermassive black holes that lurk at the centers of most spirals. There are indications that the mass of the black hole at the center of a galaxy is related to the mass of its bulge. However, this connection is still uncertain, and why these two components should be so strongly correlated is still a mystery—one that astronomers 1 / 2 APA citation: Image: Hubble gazes at fluffy-looking galaxy (2020, March 20) retrieved 29 September 2021 from https://phys.org/news/2020-03-image-hubble-fluffy-looking-galaxy.html This document is subject to copyright.

DOI: 10.1051/0004-6361/201732271 vii Abstract In hierarchical models of galaxy formation, stellar tidal streams are expected around most galaxies. Although these features may provide useful diagnostics of the LCDM model, their observational properties remain poorly constrained. Statistical analysis of the counts and properties of such features is of interest for a direct comparison against results from numeri- cal simulations. In this work, we aim to study systematically the frequency of occurrence and other observational properties of tidal features around nearby galaxies.

Hodge1∗† 1Blue Ridge Community College, 100 College Dr., Flat Rock, NC, 28731-1690 November 23, 2006 Abstract A scalar potential model (SPM) was developed from considerations of galaxy clusters and of redshift. The SPM is applied to H i rotation curves (RCs) and RC asymmetry of spiral galaxies. The resulting model adds the force of a scalar potential of the host galaxy and of neighboring galaxies to the Newtonian rotation velocity equation. The RC is partitioned radially into regions. The form of the equation for each parameter of each region is the same with differing proportionality constants. Integer values of each equation are determined empirically for each galaxy. Among the sample galaxies, the global properties of galaxies of B band luminosity, of position, and of orientation determine the RC and RC asymmetry. The Source of the scalar field acts as a monopole at distances of a few kpc from the center of spiral galaxies. The scalar potential field causes Newtonian mechanics to considerably underestimate the mass in galaxies, which is the “missing mass problem”. The SPM is consistent with RC and RC asymmetry observations of the sample spiral galaxies. Galaxies: kinematics and dynamics – Galaxies: fundamental parameters – Galaxies: interactions – Galaxies: spiral arXiv:astro-ph/0611029 v2 22 Nov 2006 1 Introduction The discrepancy between the Newtonian estimated mass in spiral galaxies and the observation of star and gas kinematics is well established.

  • Making a Sky Atlas
    Appendix A Making a Sky Atlas Although a number of very advanced sky atlases are now available in print, none is likely to be ideal for any given task. Published atlases will probably have too few or too many guide stars, too few or too many deep-sky objects plotted in them, wrong- size charts, etc. I found that with MegaStar I could design and make, specifically for my survey, a “just right” personalized atlas. My atlas consists of 108 charts, each about twenty square degrees in size, with guide stars down to magnitude 8.9. I used only the northernmost 78 charts, since I observed the sky only down to –35°. On the charts I plotted only the objects I wanted to observe. In addition I made enlargements of small, overcrowded areas (“quad charts”) as well as separate large-scale charts for the Virgo Galaxy Cluster, the latter with guide stars down to magnitude 11.4. I put the charts in plastic sheet protectors in a three-ring binder, taking them out and plac- ing them on my telescope mount’s clipboard as needed. To find an object I would use the 35 mm finder (except in the Virgo Cluster, where I used the 60 mm as the finder) to point the ensemble of telescopes at the indicated spot among the guide stars. If the object was not seen in the 35 mm, as it usually was not, I would then look in the larger telescopes. If the object was not immediately visible even in the primary telescope – a not uncommon occur- rence due to inexact initial pointing – I would then scan around for it.

Madore20 Accepted for publication in the Astrophysical Journal Supplement Series ABSTRACT The Spitzer Survey of Stellar Structure in Galaxies (S4G) is the largest available database of deep, homogeneous middle-infrared (mid-IR) images of galaxies of all types. The survey, which includes 2352 nearby galaxies, reveals galaxy morphology only minimally affected by interstellar extinction. This paper presents an atlas and classifications of S4G galaxies in the Comprehensive de Vaucouleurs revised Hubble-Sandage (CVRHS) system. The CVRHS system follows the precepts of classical de Vaucouleurs (1959) morphology, modified to include recognition of other features such as inner, outer, and nuclear lenses, nuclear rings, bars, and disks, spheroidal galaxies, X patterns and box/peanut structures, OLR subclass outer rings and pseudorings, bar ansae and barlenses, parallel sequence late-types, thick disks, and embedded disks in 3D early-type systems. We show that our CVRHS classifications are internally consistent, and that nearly half of the S4G sample consists of extreme late-type systems (mostly bulgeless, pure disk galaxies) in the range Scd-Im.

Le Verrier, 13248 Marseille, France 5 Visiting Astronomer, Canada–France–Hawaii Telescope. 28 July 2021 ABSTRACT A catalog of ionized gas velocity fields for a sample of 30 spiral and irregular galaxies of the Virgo cluster has been obtained by using three-dimensional optical data. The aim of this sur- vey is to study the influence of high density environments on the gaseous kinematics of local cluster galaxies. Observations of the Hα line by means of Fabry-Perot interferometry have been performed at the Canada-France-Hawaii, ESO 3.6m, Observatoire de Haute-Provence 1.93m and Observatoire du mont M´egantic telescopes at angular and spectral samplings from 0′′.4 to 1′′.6 and 7 to 16 km s−1. A recently developed, automatic and adaptive spatial bin- ning technique is used to reach a nearly constant signal-to-noise ratio (S/N) over the whole field-of-view, allowing to keep a high spatial resolution in high S/N regions and extend the detection of signal in low S/N regions.
