QUASAR ROLE. “Supermassive black holes (SMBHs) at the centres of galaxies are known to actively accrete, forming so-called `active galactic nuclei' (AGN) or `quasars'. These AGN are believed to feed back energy into their host galaxies, regulating star formation and the growth of the SMBH itself.” https://lnkd.in/d9BB4wDY View in LinkedIn

PLANCK DENSITY. “It is assumed that the "Planck" density of about 10(94) g/sm3, the substance of stars such changes occur, which should stop the compression of the stars to prevent endless drop to the point of singularity.” https://lnkd.in/dCUPXXmn View in LinkedIn

LARGE FAST WINDS. “High velocity (10(2)–10(3) km s−1) energy-driven winds on large scales have been recently also studied by Bieri et al. by means of radiation-hydrodynamic simulations of isolated galactic discs. They suggest that outflow rates as high as ~10(3) M⊙ yr−1 are sustained by IR radiation, with scattering on dust grains enabling efficient momentum transfer to the gas.” (IR = infrared). https://lnkd.in/dHcpNrnR View in LinkedIn

“THE POWER SOURCE for dusty galaxies. About 99% of the energy released by galaxies in the submm and far-IR wavebands is produced by thermal emission from dust grains; the remainder comes from fine-structure atomic and molecular rotational line emission. However, the source of the energy to power this emission by heating dust is often unclear.” (IR = infrared; Submm == submillimeter wavelengths). https://lnkd.in/dAkZ_ejH View in LinkedIn

HIGH ENERGY SOURCES. “The first extragalactic submm/mm surveys using SCUBA and MAMBO revealed a population of very luminous high-redshift galaxies, which as a population, were responsible for the release of a significant fraction of the energy generated by all galaxies over the history of the Universe.” (Submm == submillimeter wavelengths). https://lnkd.in/dAkZ_ejH View in LinkedIn

CHALLENGING WAVELENGTHS. “With the possible exception of the hardest X-ray wavebands, studies of distant galaxies in the submm waveband remained elusive for the longest period.” The many reasons for this difficulty are discussed.

CLEAR SEPARATION. “The detection of submm radiation from distant galaxies is one of the most recent developments in observational cosmology, and has finally brought this region of the electromagnetic spectrum into use for making cosmological observations not directly connected with the cosmic microwave background (CMB).” (Submm == submillimeter wavelengths). https://lnkd.in/dAkZ_ejH View in LinkedIn

NOVEL TERRITORY. “This review discusses the results of a new type of direct observation of the galaxy formation process, made possible by the development of powerful new radiation detectors sensitive to wavelengths in the range 200 µm to about 1 mm: the submillimeter (submm) waveband.” (Submm == submillimeter wavelengths). https://lnkd.in/dAkZ_ejH View in LinkedIn

DISEASE KNOCKOUTS. “However, the correction of this misinterpretation in no way diminishes the importance of FOXP2, given the importance of increased oro-motor control in the evolution of spoken language. Studies of affected members using noninvasive brain imaging have already begun to uncover the anatomical and physiological underpinnings of the deficits caused by the mutated allele.” https://lnkd.in/dTkGwcGB View in LinkedIn
