The Broad-Line and Narrow-Line Regions of the LINER NGC 4579
We report the discovery of an extremely broad H-alpha emission line in the LINER nucleus of NGC 4579. From ground-based observations, the galaxy was previously known to contain a Type 1 nucleus with a broad H-alpha line of FWHM = 2300 km/s and FWZI ...

The Distribution of H2O Maser Emission in the Nucleus of NGC 4945 [PDF]
We present the first interferometer map of the water maser emission in the active nucleus of NGC 4945. Although the declination of the galaxy is about -49 degrees, we were able to make the observations with the southernmost antennas of the Very Long ...

Evolution of red algal plastid genomes: ancient architectures, introns, horizontal gene transfer, and taxonomic utility of plastid markers. [PDF]
Red algae have the most gene-rich plastid genomes known, but despite their evolutionary importance these genomes remain poorly sampled. Here we characterize three complete and one partial plastid genome from a diverse range of florideophytes. By unifying

The Role of Mergers in Early-type Galaxy Evolution and Black Hole Growth [PDF]
Models of galaxy formation invoke the major merger of gas-rich progenitor galaxies as the trigger for significant phases of black hole growth and the associated feedback that suppresses star formation to create red spheroidal remnants.

Periaqueductal gray matter echogenicity as a marker of migraine chronification: a case control study
Background Migraine is one of the most prevalent and disabling medical diseases in the world. The periaqueductal gray matter and the red nucleus play an important role in its pathogenesis.

Since its founding in 1870, the Colegio Seminario San Rafael of Valparaíso has offered natural science-related courses, complemented by laboratory work. Thus, in 1881, five science “cabinets” were established within the school premises, and in 1886, the

Serendipitous discovery of the long-sought AGN in Arp 299-A
Context: The dusty nuclear regions of luminous infra-red galaxies (LIRGs) are heated by either an intense burst of massive star formation, an active galactic nucleus (AGN), or a combination of both.

Carbocyanine dye usage in demarcating boundaries of the aged human red nucleus. [PDF]
BackgroundThough the adult human magnocellular Red nucleus (mNr) is essentially vestigial and its boundaries with neighbouring structures have never been well demarcated, human studies in utero have shown a well developed semilunar mNr wrapping around ...
