Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Kostas Tzanavaris, Pau Amaro Seoane, , , | Summary: In the context of mathematical cosmology, the study of necessary and sufficient conditions for a semi-Riemannian manifold to be a (generalised) Robertson-Walker space-time is important. In particular, it is a requirement for the development of initial data […]
Kavli Affiliate: Morteza Gharib | First 5 Authors: Jeff Delaune, Jacob Izraelevitz, Larry A. Young, William Rapin, Evgeniy Sklyanskiy | Summary: Mid-Air Deployment (MAD) of a rotorcraft during Entry, Descent and Landing (EDL) on Mars eliminates the need to carry a propulsion or airbag landing system. This reduces the total mass inside the aeroshell by […]

Kavli Affiliate: Herman Marshall | First 5 Authors: Daniel Schwartz, Aneta Siemiginowska, Brad Snios, Diana Worrall, Mark Birkinshaw | Summary: We report the detection of extended X-ray emission from two high-redshift radio quasars. These quasars, J1405+0415 at $z$=3.208 and J1610+1811 at $z$=3.118, were observed in a Chandra snapshot survey selected from a complete sample of […]

Kavli Affiliate: Eli S. Rykoff | First 5 Authors: LSST Dark Energy Science Collaboration, Bela Abolfathi, David Alonso, Robert Armstrong, Éric Aubourg | Summary: We describe the simulated sky survey underlying the second data challenge (DC2) carried out in preparation for analysis of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) […]

Kavli Affiliate: P. G. Steeneken | First 5 Authors: D. Afanasiev, J. R. Hortensius, M. Matthiesen, S. Mañas-Valero, M. Šiškins | Summary: Magnetic van der Waals materials provide an ideal playground for exploring the fundamentals of low-dimensional magnetism and open new opportunities for ultrathin spin processing devices. The Mermin-Wagner theorem dictates that as in reduced […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Kaitlin C. Rasmussen, Joseph Zepeda, Timothy C. Beers, Vinicius M. Placco, Eric Depagne | Summary: We present the first release of a large-scale study of relatively bright (V < 13.5) metal-poor stars observed with the Southern African Large Telescope (SALT), based on high-resolution spectra of 50 stars […]
