Have you ever wondered how we might go about finding microscopic black holes from the dawn of time? Check out my new article for @SuperclusterHQ — my first published piece of science writing outside of @astrobites! ✨⚫️🔭 https://t.co/gry5VSCUSn

It was first proposed that black holes could form directly from the small, random density fluctuations inherent to the chaotic primordial universe. The studies from which the idea emerged — pioneered...

🚨BREAKING🚨 On 3/25 PhD Tufts grad worker Rumeysa Ozturk, a Fulbright scholar, was ambushed by ICE on her way to an Iftar w/ friends after leaving her apt. Rumeysa was likely targeted after being doxxed by Canary Mission and her home watched for 2 days before she was abducted.

From @lucasb413: If primordial black holes exist, one place we might find them is in binary systems with other objects like planets or asteroids. Today’s paper explores how common these systems might be and how to go about finding them. 🔭✨️ https://t.co/LlMQ8xpMcB

The origin of dim supernovae known as Ca-rich transients is still not well-understood. Could it be that these rare events are set off by an encounter between a white dwarf and a primordial black hole?

Black hole, why don’t you come over? White dwarf supernova, falling into me! We don’t know if it’s primordial, white dwarf supernova, fall right into me! My new bite on whether detonating white dwarfs with primordial black holes could explain some features of Ca-rich transients:

On Monday’s total solar eclipse over North America, we had over 20 Astrobites authors in the path of totality! Check out our photo-blog retrospective of the day here:
astrobites.org
Astrobites Authors bring to you firsthand accounts of the action on the path of totality, and the surreal experience of watching the celestial shadow.

"As astronomers, we must raise our voices when the futures of our colleagues (present & future) are stripped away from them. As humans, we must take action when we bear witness to extreme violence and cultural erasure of our fellow humans." Please take a moment to read our post:
From @astrobites: The genocide in Gaza demands our attention and our action. As astronomers and members of the global scientific community, we cannot ignore the immense suffering and devastation inflicted upon our colleagues. https://t.co/2LHTdapqXM

New @astrobites post from me! Join me in learning about one of the strangest ideas in multimessenger astrophysics I’ve seen to date
From @lucasb413: What if we could use continuous gravitational waves from far away pulsars to learn about the inside of our very own sun? The authors of today’s paper explore what it would take to make this far-out idea a reality.

Giant black holes were supposed to be bit players in the early cosmic story. But recent James Webb Space Telescope observations are finding an unexpected abundance of the beasts.
