We study the stellar response in a spectrum of potentials describing the barred spiral galaxy NGC1300. These potentials have been presented in a previous paper and correspond to three different assumptions as regards the geometry of the galaxy. For each potential we consider a wide range of Ω ...
Pictures and descriptions of New General Catalog Objects NGC 1300, NGC 1301, NGC 1302, NGC 1303, NGC 1304, NGC 1305, NGC 1306, NGC 1307, NGC 1308, NGC 1309, NGC 1310, NGC 1311, NGC 1312, NGC 1313, NGC 1314, NGC 1315, NGC 1316, NGC 1317, NGC 1318, NGC 131
NGC 1300 has most of its star formation. That is where you find most of the galaxy's pink nebulas and young blue stars. That is where the incubator of NGC 1300 hatches the majority of its new stars. That is where NGC 1300 is growing in size - at the ends of its bar. And that ...
Below, a 1.5 arcmin wide SDSS image of the galaxy NGC 7002 (= PGC 66009) Discovered (Sep 30, 1834) by John Herschel A magnitude 12.4 elliptical galaxy (type E2?) in Indus (RA 21 03 44.8, Dec -49 01 47) Historical Identification: Per Dreyer, NGC 7002 (= GC 4623 = JH 3848, ...

仙女星系(英语:Andromeda Galaxy;M31;NGC 224;曾被称为仙女座大星云),位于仙女座方位的拥有巨大盘状结构的旋涡星系,梅西耶星表编号为M31,星云星团新总表编号位NGC 224,直径22万光年,距离地球有254万光年,是距银河系最近的大星系。仙女星系和银河系同处于本星系群,直径至少是银河系的1.6倍。仙女星系是本星系群中...
The half-light radius of the inner component alone is estimated as 6 kpc, suggesting a significantly smaller size of this galaxy in the past. This may be the local stellar population signature of the size evolution found for early-type galaxies from high-redshift observations....
We subtract the underlying stellar continuum from the galaxy spectra and fit the emission lines. With these methods, we derive and analyze emission line and kinematic maps. Emission line ratio maps are examined by means of diagnostic diagrams. Results. The central few kpc of NGC 5850 are ...
NASA在3月9日发布的新闻稿中指出，韦伯太空望远镜的近红外相机和中红外仪器（MIRI）分别拍到恒星形成区NGC 604的两张新图。NGC 604位于三角座星系（Triangulum galaxy，又称M33）中，距离地球273万光年。这个恒星形成区的年龄估计有350万年，它的发光气体云绵延大约1,300光年。在这些图片中，状似巨穴的气泡和延伸的...
