NGC 2776 is an intermediate spiral galaxy located in the constellation of Lynx. The redshift of the galaxy is (z) 0.0087[1] and it was discovered in March 1828 by the British astronomer named John Herschel, who described it as a bright object, round with a bright middle.[3]
Description
[edit]NGC 2776 is classified as an isolated spiral galaxy of type SAB(rs)c[4] or an early type Sc that is described as face-on.[5] The galaxy shows the presence of spiral arms considered as fragmented, with star formation activity as seen in optical imaging.[4] These arms appear to emerge from a smooth inner disk on the outer edge with high surface brightness.[6] One of the arms appear to be blue; this also corresponds to an approximate stellar age of less than 107 years.[7] The central nucleus of the galaxy has a bright appearance.[8]
There is also a central region present in the galaxy with a reddened appearance and described as elongated.[4][9] An inner ring feature is shown based on JHK imaging.[4] A weak bar feature is suggested, although a study published in June 1997 suggested it lacks a bar.[9][10] Regions of H II have also been detected inside the galaxy.[7]
The supermassive black hole lying inside the center of the galaxy is estimated to be 6.9 M☉, based on a study of low-luminosity galaxies published in 2007.[11]
