Hypothalamic Astrocytes Exhibit Glycolytic Features Making Them Prone for Glucose Sensing
Glia, EarlyView.Hypothalamic astrocytes versus cortical astrocytes: are more glycolytic due to high Pkm2, Glut1 and Mct4 expression do not exhibit glutamate‐induced glycolysis detect glucose concentration variations via an AMPK sensor with altered lactate production. ABSTRACT In the hypothalamus, detection of energy substrates such as glucose is essential to regulate ...

The Subaru high-z quasar survey: discovery of faint z~6 quasars
, 2014 We present the discovery of one or two extremely faint z~6 quasars in 6.5 deg^2 utilizing a unique capability of the wide-field imaging of the Subaru/Suprime-Cam.

The Discovery of a Luminous Broad Absorption Line Quasar at a Redshift of 7.02 [PDF]
Astrophysical Journal, 2018 Despite extensive efforts, to date only two quasars have been found at z > 7, due to a combination of low spatial density and high contamination from more ubiquitous Galactic cool dwarfs in quasar selection. This limits our current knowledge of the super-

A flux-ratio anomaly in the CO spectral line emission from gravitationally-lensed quasar MG J0414+0534 [PDF]
, 2018 We present an analysis of archival observations with the Atacama Large (sub-)Millimetre Array (ALMA) of the gravitationally lensed quasar MG J0414+0534, which show four compact images of the quasar and an Einstein ring from the dust associated with the ...

The Physical Relation between Disc and Coronal Emission in Quasars
Frontiers in Astronomy and Space Sciences, 2018 We propose a modified version of the observed non-linear relation between the X-ray (2 keV) and the ultraviolet (2,500 Å) emission in quasars (i.e., LX∝LUVγ) which involves the full width at half-maximum, FWHM, of the broad emission line, i.e., LX∝LUVγ ...

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 544-569, March 2025.Abstract Refractory inclusions (RIs) in chondrites are widely used as tracers of early solar system formation conditions. In the context of sample‐return missions, a non‐destructive and non‐invasive analytical tool that can rapidly detect and characterize RIs in space samples during their early phase of study is highly needed.

The Jets in Micro-Quasars and Quasars: A Comparison [PDF]
Highlights of Astronomy, 2005 AbstractThe discovery of relativistic jets in radio emitting X-ray binaries in our own galaxy has led to the term ‘microquasar’ being coined for these objects. In this paper the properties of microquasars are compared with those of quasars and radio galaxies, with the aim of trying to see how the similarities and differences can inform us about the ...
