Tracing Large Scale Structure with 270 Million Galaxies
Today’s PRJ letter presents the largest mass map to date, highlighting large scale structure in the Universe!
Primordial Black Holes lensing my Andromeda Galaxy? It could be more common than you think
We’re not sure if Primordial Black Holes (PBHs) exist, but today’s authors might have seen evidence of them while observing the Andromeda Galaxy — and not just one PBH, but twelve!
Zig-zagging across the universe
What’s better than a single gravitational lens? A double gravitational lens! Learn about how light from a distant quasar zig-zags across the universe because of the first double gravitational lens to be observed!
Echoes in the Black Hole Night
It’s like you’re shouting at the Grand Canyon, but 800 million light years away.
Holy Cow! Is our journey through the universe the reason for the Hubble Tension?
We move through the universe relative to the Cosmic Microwave Background. Could our movement cause our measurements of the Hubble constant to be biased?
How Good are Humans at Visually Identifying Gravitational Lenses?
In an era of increasing reliance on computers to classify astrophysical imagery, what role do humans have to play? Today’s paper examines human biases in visual searches for gravitational lensing.
