A Basic Requirement for Studying the Heavens Is Determining Where In
Abasic requirement for studying the heavens is determining where in the sky things are. To specify sky positions, astronomers have developed several coordinate systems. Each uses a coordinate grid projected on to the celestial sphere, in analogy to the geographic coordinate system used on the surface of the Earth. The coordinate systems differ only in their choice of the fundamental plane, which divides the sky into two equal hemispheres along a great circle (the fundamental plane of the geographic system is the Earth's equator) . Each coordinate system is named for its choice of fundamental plane. The equatorial coordinate system is probably the most widely used celestial coordinate system. It is also the one most closely related to the geographic coordinate system, because they use the same fun damental plane and the same poles. The projection of the Earth's equator onto the celestial sphere is called the celestial equator. Similarly, projecting the geographic poles on to the celest ial sphere defines the north and south celestial poles. However, there is an important difference between the equatorial and geographic coordinate systems: the geographic system is fixed to the Earth; it rotates as the Earth does . The equatorial system is fixed to the stars, so it appears to rotate across the sky with the stars, but of course it's really the Earth rotating under the fixed sky. The latitudinal (latitude-like) angle of the equatorial system is called declination (Dec for short) . It measures the angle of an object above or below the celestial equator. The longitud inal angle is called the right ascension (RA for short). -

Outflows in the Seyfert 2 Galaxy NGC 5643 Traced By
Publications of the Astronomical Society of Australia (2018), 35, e040, 8 pages doi:10.1017/pasa.2018.31 Research Paper Outflows in the Seyfert 2 galaxy NGC 5643 traced by the [S III] emission Rogemar A.

Freitas1,2 1Departamento de Física, CCNE, Universidade Federal de Santa Maria, Santa Maria, 97105-900 RS, Brazil and 2Colégio Politécnico, Universidade Federal de Santa Maria, Santa Maria, 97105-900 RS, Brazil Abstract We use Gemini Multi-Object Spectrograph Integral Field Unit observations of the inner 285 × 400 pc2 region of the Seyfert 2 galaxy NGC 5643 to map the [S III]λ9069 emission line flux distribution and kinematics, as well as the stellar kinematics, derived by fitting the Ca IIλλλ8498,8542,8662 triplet, at a spatial resolution of 45 pc. The stellar velocity field shows regular rotation, with a projected velocity of − ◦ − 100 km s 1 and kinematic major axis along a position angle of –36 . A ring of low stellar velocity dispersion values (∼70 km s 1), attributed to young/intermediate age stellar populations, is seen surrounding the nucleus with a radius of 50 pc. We found that the [S III] flux distribu- tion shows an elongated structure along the east–west direction and its kinematics is dominated by outflows within a bi-cone at an ionised − gas outflow rate of 0.3 M yr 1. In addition, velocity slices across the [S III]λ9069 emission line reveal a kinematic component attributed to rotation of gas in the plane of the galaxy.

Deep Sky Explorer Atlas
Deep Sky Explorer Atlas Reference manual Star charts for the southern skies Compiled by Auke Slotegraaf and distributed under an Attribution-Noncommercial 3.0 Creative Commons license. Version 0.20, January 2009 Deep Sky Explorer Atlas Introduction Deep Sky Explorer Atlas Reference manual The Deep Sky Explorer’s Atlas consists of 30 wide-field star charts, from the south pole to declination +45°, showing all stars down to 8th magnitude and over 1 000 deep sky objects. The design philosophy of the Atlas was to depict the night sky as it is seen, without the clutter of constellation boundary lines, RA/Dec fiducial markings, or other labels. However, constellations are identified by their standard three-letter abbreviations as a minimal aid to orientation. Those wishing to use charts showing an array of invisible lines, numbers and letters will find elsewhere a wide selection of star charts; these include the Herald-Bobroff Astroatlas, the Cambridge Star Atlas, Uranometria 2000.0, and the Millenium Star Atlas. The Deep Sky Explorer Atlas is very much for the explorer. Special mention should be made of the excellent charts by Toshimi Taki and Andrew L. Johnson. Both are free to download and make ideal complements to this Atlas. Andrew Johnson’s wide-field charts include constellation figures and stellar designations and are highly recommended for learning the constellations. They can be downloaded from http://www.cloudynights.com/item.php?item_id=1052 Toshimi Taki has produced the excellent “Taki’s 8.5 Magnitude Star Atlas” which is a serious competitor for the commercial Uranometria atlas. His atlas has 149 charts and is available from http://www.asahi-net.or.jp/~zs3t-tk/atlas_85/atlas_85.htm Suggestions on how to use the Atlas Because the Atlas is distributed in digital format, its pages can be printed on a standard laser printer as needed. -

New H2O Masers in Seyfert and FIR Bright Galaxies IV

Tarchi1,P.Castangia1,C.Henkel2,G.Surcis3,, and K. M. Menten2 1 INAF-Osservatorio Astronomico di Cagliari, Loc. Poggio dei Pini, Strada 54, 09012 Capoterra (CA), Italy e-mail: [email protected] 2 Max-Planck-Insitut für Radioastronomie, Auf dem Hügel 69, 53121 Bonn, Germany 3 Argelander-Institut für Astronomie der Universität Bonn, Auf dem Hügel 71, 53121 Bonn, Germany Received 1 April 2010 / Accepted 23 August 2010 ABSTRACT Context. Very luminous extragalactic water masers, the megamasers, are associated with active galactic nuclei (AGN) in galaxies characterized by accretion disks, radio jets, and nuclear outflows. Weaker masers, the kilomasers, seem to be related mostly to star formation activity, although the possibility exists that some of these sources may belong to the weak tail of the AGN maser distribution. Aims. It is particularly important to accurately locate the water maser emission to reveal its origin and shed light on extragalactic star- forming activity or to elucidate the highly obscured central regions of galaxies. Methods. We performed interferometric observations of three galaxies, NGC 3556, Arp 299, and NGC 4151, where water emission was found. Statistical tools were used to study the relation between OH and H2O maser emission in galaxies. Results. The maser in NGC 3556 is associated with a compact radio continuum source that is most likely a supernova remnant or radio supernova. In Arp 299, the luminous water maser has been decomposed in three main emitting regions associated with the nuclear regions of the two main galaxies of the system, NGC 3690 and IC 694, and the region of overlap. -
