Contribution of gravitational redshift to spectral line ~ The authors analyse the influence of gravitational redshift on the spectral line profiles of homogeneous static and optically thin region near massive AGN Seyfert galaxies and quasars The correction function that determines the degree of spectral line profile distorsion produced by gravitational field has been investigated
Black Hole Nurtures Baby Stars a Million LightYears Away ~ On October 3 2003 the galaxy NGC 7319 was measured to have a redshift of z 00225 It is not uncommon for “nearby” galaxies to have redshifts below z 1 However a quasar was located in front of NGC 7319’s opaque gas clouds with an observed redshift of z 2114 And more evidence of intrinsic redshift
Quasars and Active Galactic Nuclei ~ 132 Gravitational redshift Einsteins general theory of relativity drew the attention of astronomers to this source of redshift indeed the early demonstrations of this effect were for the white dwarf stars Sirius B and Eridani B In either case the effect was very small being less than 0001
Active galactic nuclei PNAS ~ Active galactic nuclei are the most powerful longlived objects in the Universe Recent data confirm the theoretical idea that the power source is accretion into a massive black hole The common occurrence of obscuration and outflows probably means that Gravitational redshift due to the deep potential well accounts for part of the skewness
Active Galactic Nuclei Influence the Genesis of Galaxies ~ The quasar and the supermassive black hole form active galactic nuclei AGN The combination of quasars and its black hole engine formed large accretion disks as matter from the quasar A considerable amount of matter from the accretion disk escaped the gravitational pull from the event horizon of the black hole This
A possible influence on standard model of quasars and ~ Recent observational evidence indicates that the center of our Milky Way galaxy harbors a supermassive object with ultrastrong radial magnetic field Eatough et al in Nature 591391 2013 Here we demonstrate that the radiations observed in the vicinity of the Galactic Center GC Falcke and Marko in arXiv13111841v1 2013 cannot be emitted by the gas of the accretion disk since the
Astronomy Ch 17 Practice Questions Flashcards Quizlet ~ C Extreme redshift of light from stars near the centers of these galaxies caused by gravitational redshift from a very massive object D Observation that these galaxies are rushing rapidly toward each other and in at least one case toward the Milky Way because of the gravitational attraction between these very large masses
On the Evolution of HighRedshift Active Galactic Nuclei ~ On the Evolution of HighRedshift Active Galactic Nuclei Jirong Mao123 and Minsun Kim3 jirongmaocn ABSTRACT We build a simple physical model to study the highredshift active galactic Nucleus AGNevolution within the coevolution framework ofcentral black holes BHs and their host galaxies The correlation between the circular
Active galactic nuclei PubMed Central PMC ~ Active galactic nuclei AGN involve the most powerful steady sources of luminosity in the Universe They range from the nuclei of some nearby galaxies emitting about 10 40 erg⋅s −1 1 erg 01 μJ to distant quasars emitting more than 10 47 erg⋅s −1
Black holes Active Galaxies Diagram Quizlet ~ an object of very high redshift that looks like a star but is extragalactic and highly luminous also called a quasi active galactic nuclei AGN galaxies that are almost as luminous as quasars and share many of their properties although to a less spectacular degree abnormal amounts of energy are produced in their centers
