If you had $100 million, how would you look for aliens?
Today’s authors look for signs of intelligent life at the center of our galaxy. No aliens yet… but still some cool science!
Dwarfs from ELVES: The structure of dwarf satellite galaxies
How does the structure of the smallest galaxies vary with different environments? Today’s authors use the ELVES survey to investigate!
Solving the Hubble tension might require more than changing the early Universe
One of the most important issues in cosmology is the Hubble tension – why do different probes not agree on how fast the Universe is expanding? A popular solution is changing the physics in the very early Universe. Today’s paper explores, why this approach might not work, by measuring the expansion rate with observables independent of the early Universe.
Our Galaxy is Shook: Impact of the LMC on the Outer Milky Way
Today’s paper looks at the gravitational influence of the Large Magellanic Cloud on the Milky Way – one may think our Galaxy is in equilibrium, but it is actually being sloshed around!
UR: Measuring the Hubble Constant With Dynamical Tides In Inspiraling Neutron Star Binaries
In this #UndergradResearch post, James Sunseri explores the possibility of using gravitational waves from colliding neutron stars to measure the Hubble Constant without observing the electromagnetic spectrum.
