Active galaxies and radiative heating
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2005 There is abundant evidence that heating processes in the central regions of elliptical galaxies have both prevented large–scale cooling flows and assisted in the expulsion of metal rich gas. We now know that each such spheroidal system harbours in its core a massive black hole weighing ca.J. P.

The Astrophysical Journal Letters, 2023 We present mid-infrared spectroscopic observations of the nucleus of the nearby Seyfert galaxy NGC 7469 taken with the MIRI instrument on the James Webb Space Telescope (JWST) as part of Directors Discretionary Time Early Release Science program 1328 ...L.

The Astrophysical Journal, 2023 Active dwarf galaxies are important because they contribute to the evolution of dwarf galaxies and can reveal their hosted massive black holes. However, the sample size of such sources beyond the local universe is still highly limited.Fan Zou, W. N. Brandt, Qingling Ni, Shifu Zhu, David M. Alexander, Franz E. Bauer, Chien-Ting J.

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2005 Two lines of evidence indicate that active galaxies, principally radio galaxies, have heated the diffuse hot gas in clusters. The first is the general need for additional heating to explain the steepness of the X–ray luminosity–temperature relation in clusters, the second is to solve the cooling–flow problem in cluster cores.openaire +3 more sourcesGalaxy Zoo:dust in spiral galaxies [PDF]
, 2010 We investigate the effect of dust on spiral galaxies by measuring the inclination dependence of optical colours for 24 276 well-resolved Sloan Digital Sky Survey (SDSS) galaxies visually classified via the Galaxy Zoo project.Masters, Karen L., Murray, P, Bamford, S, Slosar, Anze, Thomas, Daniel Georg, Vandenberg, J, Keel, WC, Bamford, Steven, Szalay, Alexander S., Mosleh, Moein, Andreescu, Dan, Bamford, Steven P., Andreescu, D, Thomas, Daniel, Thomas, D, Nichol, Robert, Nichol, R, Edmondson, Edward M., Vandenberg, Jan, Murray, Phil, Lintott, Chris J., Schawinski, Kevin, Masters, KL, Schawinski, K, Raddick, MJ, Keel, William C., Szalay, AS, Mosleh, M, Edmondson, EM, Slosar, A, Lintott, CJ, Raddick, M.

Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT The Sloan Digital Sky Survey (SDSS) has proved to be a powerful resource for understanding the physical properties and chemical composition of star-forming galaxies in the local Universe. The SDSS population of active galactic nuclei (AGNs) remains as of yet less explored in this capacity.Flury, Sophia R., Moran, Edward C.openaire +2 more sourcesEuclid Quick Data Release (Q1)
Astronomy & AstrophysicsActive galactic nuclei (AGN) are an important phase in galaxy evolution. However, they can be difficult to identify due to their varied observational signatures.Margalef-Bentabol B., Wang L., La Marca A., Rodriguez-Gomez V., Humphrey A., Fotopoulou S., Ricci F., Toba Y., Stevens G., Mezcua M., Roster W., Knapen J.
