Abell S1063 is so massive that the light from distant galaxies bends around it, allowing it to act as a magnifying glass to ...

However, the USTC researchers have revealed that dark matter halos hosting dwarf galaxies also exhibit halo bias, which is ...

Dark matter is more than five times as abundant as all the visible matter in the universe. So why can't we see any of it?

Now, using a method called weak gravitational lensing, scientists think they've finally found the hidden intruder. The Perseus galaxy cluster is one of the most massive structures in the known ...

It is known as weak gravitational lensing, and while it is a minute effect, it can be seen. "This is the missing piece we’ve been looking for," Dr James Jee, corresponding author of the study ...

Using weak gravitational lensing, Rubin will map dark matter with unparalleled precision. This technique measures how massive foreground galaxies bend light from distant background galaxies, creating ...

Amara expects it to find hundreds of thousands of strong lenses over the next six years, along with many examples of weak gravitational lensing. The sheer number of resplendent astrophysical ...

And once again, when combined with other datasets—from CMB, supernovae, and weak gravitational lensing studies—strong hints emerged that dark energy might be changing over time. The confidence ...

Sven Heydenreich, a postdoctoral research scholar at UC Santa Cruz, is co-leading the effort to combine these measurements under the rationale that the ones made by DESI and those measuring weak ...

or CMB), exploding stars (supernovae), and how light from distant galaxies is warped by gravity (weak gravitational lensing). The collaboration shared its findings March 19 in multiple papers ...

For us to better probe dark energy, the spacecraft will need to look for a more subtle type of "weak" gravitational lensing than Einstein Rings—one in which the background galaxies appear only ...
