Astronomers Use Gravitational Lensing to Measure Hubble Constant

HE0435-1223, located in the centre of this wide-field image, is among the five best lensed quasars discovered to date. The foreground galaxy creates four almost evenly distributed images of the distant quasar around it. Image credit: NASA / ESA / Hubble / S.H. Suyu et al.
Jan 27, 2017 by News Staff

Astronomers from the international H0LiCOW (H0 Lenses in COSMOGRAIL’s Wellspring) collaboration have made a new measurement of the Hubble constant — a fundamental quantity that describes the rate at which the Universe is expanding — and it doesn’t quite line up with a different estimate of the same number. That discrepancy could hint at ‘new physics’ beyond the Standard Cosmological Model. RXJ1131-1231 is among the five best lensed...

The six most common elements of life on Earth (including more than 97% of the mass of a human body) are carbon, hydrogen, nitrogen, oxygen, sulfur and phosphorus. The colors in the spectra show dips, the size of which reveal the amount of these elements in the atmosphere of a star. The human body on the left uses the same color coding to evoke the important role these elements play in different parts of our bodies, from oxygen in our lungs to phosphorous in our bones (although in reality all elements are found all across the body). In the background is an artist’s impression of the Galaxy, with cyan dots to show the APOGEE measurements of the oxygen abundance in different stars; brighter dots indicate higher oxygen abundance.
