Kavli Affiliate: Daniel E. Holz | First 5 Authors: Kristen Schumacher, Colm Talbot, Daniel E. Holz, Nicolás Yunes, | Summary: In some beyond-Einstein theories of gravity, gravitational waves can contain up to six polarizations, which are allowed to propagate at different speeds faster than light. These different propagation speeds imply that polarizations generated by the […]
Kavli Affiliate: David W. Miller | First 5 Authors: Gabe Hoshino, Stefan Knirck, Mohamed H. Awida, Gustavo I. Cancelo, Simon Corrodi | Summary: We present the results from the first axion-like particle search conducted using a dish antenna. The experiment was conducted at room temperature and sensitive to axion-like particles in the $44-52,mumathrm{eV}$ range ($10.7 […]

Kavli Affiliate: Joshua Frieman | First 5 Authors: Jason Poh, Ashwin Samudre, Aleksandra Ćiprijanović, Joshua Frieman, Gourav Khullar | Summary: The large number of strong lenses discoverable in future astronomical surveys will likely enhance the value of strong gravitational lensing as a cosmic probe of dark energy and dark matter. However, leveraging the increased statistical […]

Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Jonah Kudler-Flam, Gautam Satishchandran, Robert M. Wald, | Summary: We consider an experimentalist, Alice, who creates a quantum superposition of a charged or massive body outside of a black hole (or, more generally, in the presence of a Killing horizon). It was previously […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Quinn O. Casey, Burçin Mutlu-Pakdil, David J. Sand, Andrew B. Pace, Denija Crnojevic | Summary: We present deep Magellan$+$Megacam imaging of Centaurus I (Cen I) and Eridanus IV (Eri IV), two recently discovered Milky Way ultra-faint satellites. Our data reach $sim2-3$ magnitudes deeper than the discovery […]

Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Anibal D. Medina, Nicolás I. Mileo, Alejandro Szynkman, Santiago A. Tanco, Carlos E. M. Wagner | Summary: Gauge anomalous quantum field theories are inconsistent as full UV theories since they lead to the breaking of Lorentz invariance or Unitarity, as well as non-renormalizability. It is […]
Kavli Affiliate: Lindsey E. Bleem | First 5 Authors: Guillaume Mahler, Keren Sharon, Matthew Bayliss, Lindsey. E. Bleem, Mark Brodwin | Summary: We report the results from a study of two massive ($M_{500c} > 6.0 times 10^{14} M_{odot}$) strong lensing clusters selected from the South Pole Telescope cluster survey for their high Einstein radius ($R_E […]
