Within the core, there may exist another body, directly seen so far only in our Galaxy and the most nearby galaxies, M 31 and M 32 (and possibly a We present axisymmetric, orbit superposition models for 12 galaxies using data taken with the Hubble Space Telescope (HST) and ground-based observatories.

In each galaxy, we detect a central black hole (BH) and measure its mass to accuracies ranging from 10% to The implications of these results on our understanding of the occurrence and morphology of massive star formation, as well as non-stellar activity, in the central regions of galaxies are :// Secular evolution is essentially a mechanism for transfer of material from the disk to the central regions of galaxies (i.e., the bulge or nucleus) via angular momentum transfer to the outer regions and redistribution of gas.

This structure can be viewed as consisting of six separate parts: (1) a nucleus, (2) a central bulge, (3) a disk (both a thin and a thick disk), (4) spiral arms, (5) a spherical component, and (6) a massive halo.

Some of these components blend into each :// [/caption] Many spiral galaxies are known to harbor bars.

Here I show that this empirical relation is consistent with a simple model where We have analysed a new high-resolution e-MERLIN GHz radio continuum map together with HST and SDSS imaging of NGCan elliptical galaxy hosting radio jets, aiming to understand the galaxy’s central structure and its connection to the nuclear activity.

We decomposed the composite HST + SDSS surface brightness profile of the galaxy into an inner stellar disc, a spheroid, and an outer As we have repeatedly said, this is true for the subatomic, atomic, mineral, plant, animal, human, planet, star, galaxy and universe. In the case of galaxies, of which we are studying here, the standing wave patterns of geometry sit still in the ‘aether’ (remember, it is a dynamic steady-state universe).

It could be the result of a natural asymmetry of the central regions of the parent galaxy in the density distribution due to rotation, or connected with the presence of a magnetic field either pre-existing, or amplified by a rotating massive object.

The word galaxy is derived from the Greek galaxias (γαλαξίας), literally "milky", a reference to the Milky es range in size from dwarfs with just a few thousand (10 3) stars to giants with one hundred trillion (10 14) stars, each orbiting their galaxy's own center Bothun and Dressler similarly explain blue H I poor disk galaxies found in the central regions of the Coma Cluster via ram pressure effects.

With computer simulations, it is shown in the present work that the tidal field of the cluster as a whole is physically sufficient to trigger cluster spiral nuclear more» We can see giant elliptical galaxies in these central regions but few, if any, spiral galaxies.

The spirals that do exist generally occur on the outskirts of clusters. We might say that ellipticals are highly “social”: they are often found in groups and very much enjoy “hanging "The intense star-forming events needed to make globular clusters generally make a galaxy less, rather than more diffuse, so understanding how we get globular clusters in ultra-diffuse galaxies is The galaxy NGCwhich is roughly half as wide as the Milky Way galaxy, has several arms that spiral outwards – like many other spiral galaxies.

This also has a central bar-like structure that is dense with stars. Only about half of all the known spiral galaxies have a central bar-like :// The galaxy-halo connection of emission-line galaxies in IllustrisTNG Boryana Hadzhiyska, Sandro Tacchella, The mass of a galaxy’s supermassive black hole is correlated with certain properties of the galaxy’s central regions, such as its total mass and the velocities of stars in the ://   The Antennae Galaxies are an example of a starburst galaxy occurring from the collision of NGC /NGC Credit: NASA/ESA.

A starburst galaxy is a galaxy undergoing an exceptionally high rate of star formation, as compared to the long-term average rate of star formation in the galaxy or the star formation rate observed in most other example, the star formation rate of the We compare Hubble Space Telescope visible-light (left) and Chandra X-ray (right) images of the central regions of NGCa galaxy about million light-years away.

It is a prime example of a galaxy in which stars are forming, evolving, and exploding at an exceptionally rapid rate due to a relatively recent merger (30 million years ago).

They lie between elliptical and spiral galaxies. With similar properties to the elliptical galaxy, they lack dust and gas with no sign of HII regions, i.e., no star formation.
