We present the results of a wide-field spectroscopic analysis of the galaxy population of the massive cluster MACSJ+ and the surrounding filamentary.   As we saw earlier, observations now show that all the galaxies with a spherical concentration of stars—either elliptical galaxies or spiral galaxies with nuclear bulges (see the chapter on Galaxies)—harbor one of these giant black holes at their centers.

We present a new model of spectrophotometric evolution for galaxies which allows us to compute evolving synthetic spectra with few assumptions about the star formation history of the galaxy. These synthetic spectra can be directly compared with observational spectra, or with apparent magnitudes and colors after convolution with the filter Cited by: The author has conducted a major new spectrophotometric survey of giant elliptical galaxies in order to measure changes due to spectral evolution.

The data set consists of good spectrophotometry on 33 galaxies to a redshift of z = The look-back time for this redshift, H 0 ≈ 50 km s -1 Mpc.

The study of the origin and evolution of galaxies and the quasar phenomenon has only just begun.

Gentle encounters between two gassy disk galaxies are possible, and these encounters leave their fundamental stellar distributions unchanged but result in the gas being swept out, thus. Almost all the currently favored models of how large-scale structure formed in the universe tell a story similar to that for individual galaxies: tiny dark matter “seeds” in the hot cosmic soup after the Big Bang grew by gravity into larger and larger structures as cosmic time ticked on (Figure ).The final models we construct will need to be able to explain the size, shape, age.

Divided into three different sections, the author first describes the data currently available at different frequencies, from X-rays to UV, optical, infrared and radio, and discusses the different emission processes and the nature of the emitting sources.

Initially, brown dwarfs were given spectral classes like M10 + or “much cooler than M9,” but so many are now known that it is possible to begin assigning spectral types. The hottest brown dwarfs are given types L0–L9 (temperatures in the range – K), whereas still cooler (– K) objects are given types T0–T9 (see Figure.

The universe now is billion years old. The color of a galaxy is an indicator of the age of the stars that populate it. Blue galaxies must contain a lot of hot, massive, young stars. Galaxies that contain only old stars tend to be yellowish red. The first generation of stars formed when the universe was only a few hundred million years old.

The main topics addressed are the contribution of emission lines to the optical light of galaxies through cosmic time, the star formation rates of actively star-forming galaxies and quenched galaxies, and the evolution of the stellar ages of galaxies from 10 billion years ago to the current time.

Large galaxies are prevented by their central black hole to form further stars (Figure 2), causing their spectral colors to rapidly turn from blue to red.

“Our elliptical galaxies would become much too massive without black holes, because the energy of ordinary supernovae is insufficient to quench their star formation”, explains Dr.

Observations show that the spectral lines of distant galaxies are redshifted, and that their recession velocities are proportional to their distances from us, a relationship known as Hubble’s law. The rate of recession, called the Hubble constant, is approximately 22 kilometers per second per million light-years.

Thus, galaxies came first and stars formed within them. Astronomers have pieced together the evolution of galaxies not from any one particular galaxy, because of the enormous time scales involved, but by reference to many galaxies in different stages.

It is possible, for example, to note common characteristics in all spiral galaxies. Several new dwarf galaxies have also been found near the Andromeda galaxy.

Such dwarf galaxies are difficult to find because they typically contain relatively few stars, and it is hard to distinguish them from the foreground stars in our own Milky Way. Figure is a rough sketch showing where the brighter members of the Local Group are located.

Using four different suites of cosmological simulations, we generate synthetic spectra for galaxies with different Lyman continuum escape fractions (fesc) at redshifts z=, in the rest-frame wavelength range relevant for the James Webb Space Telescope (JWST) NIRSpec instrument.
