Sagittarius Tidal Debris 90 kpc from the Galactic Center
, 2003 A new overdensity of A-colored stars in distant parts of the Milky Way's stellar halo, at a dereddened SDSS magnitude of g_0 = 20.3, is presented. Identification of associated variable RR Lyrae candidates supports the claim that these are blue horizontal

Simulations of imaging the event horizon of Sagittarius A* from space [PDF]
Astronomy & Astrophysics, 2019 Context. It has been proposed that Very Long Baseline Interferometry (VLBI) at submillimeter waves will allow us to image the shadow of the black hole in the center of our Milky Way, Sagittarius A* (Sgr A*), and thereby test basic predictions of the ...

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas
American Journal of Botany, EarlyView.Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Metallicity and α-Element Abundance Gradients along the Sagittarius Stream as Seen by APOGEE [PDF]
Astrophysical Journal, 2019 Using 3D positions and kinematics of stars relative to the Sagittarius (Sgr) orbital plane and angular momentum, we identify 166 Sgr stream members observed by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) that also have Gaia DR2 ...

The history of anatomical engagement
Anatomical Sciences Education, EarlyView.Abstract The public's fascination with anatomy has evolved over time and progressed from avoidance of the tainted yet saintly corpse, to their fascination with cabinets of curiosities. The current narrative review explores public engagement (PE), from its potential origins as cave paintings, to the rise of the disciplinarity of anatomy.

Mapping Observations of Peptide-like Molecules around Sagittarius B2
The Astrophysical JournalPeptide-like molecules, which have a close connection with the origin of life, have been detected in the Universe. Mapping observations of HCONH _2 and CH _3 CONH _2 , two of the simplest peptide-like molecules, are performed toward the Sagittarius B2 ...
