Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Zeyad Elsaraf, Faheem A. Khan, Qasim Zeeshan Ahmed, , | Summary: Achieving significant performance gains both in terms of system throughput and massive connectivity, non-orthogonal multiple access (NOMA) has been considered as a very promising candidate for future wireless communications technologies. It has already received serious consideration […]
Kavli Affiliate: Jeffrey A. Harvey | First 5 Authors: Zihni Kaan Baykara, Jeffrey A. Harvey, , , | Summary: We extend the investigation of special toroidal compactifications of heterotic string theory for which the half-BPS states provide representations of subgroups of the Conway group. We also explore dual descriptions of these theories and find that […]
Kavli Affiliate: Erin A. Kara | First 5 Authors: Christopher S. Reynolds, Robyn N. Smith, Andrew C. Fabian, Yasushi Fukazawa, Erin A. Kara | Summary: NGC1275 is the Brightest Cluster Galaxy (BCG) in the Perseus cluster and hosts the active galactic nucleus (AGN) that is heating the central 100,kpc of the intracluster medium (ICM) atmosphere […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Yu Qiu, Haojie Hu, Kohei Inayoshi, Luis C. Ho, Tamara Bogdanovic | Summary: Warm ionized and cold neutral outflows with velocities exceeding $100,{rm km,s}^{-1}$ are commonly observed in galaxies and clusters. Theoretical studies however indicate that ram pressure from a hot wind, driven either by the central […]
Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Fuhu Che, Qasim Zeeshan Ahmed, Faheem A. Khan, Pavlos I. Lazaridis, | Summary: With the rapid development of the Internet of Things (IoT), Indoor Positioning System (IPS) has attracted significant interest in academic research. Ultra-Wideband (UWB) is an emerging technology that can be employed for IPS as […]
Kavli Affiliate: Craig Hogan | First 5 Authors: Kris Mackewicz, Craig Hogan, , , | Summary: A linear analytical solution is derived for the gravitational shock wave produced by a particle of mass $M$ that decays into a pair of null particles. The resulting space-time is shown to be unperturbed and isotropic, except for a […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Weiwei Xu, Huanyuan Shan, Ran Li, Chunxiang Wang, Linhua Jiang | Summary: The concentration-mass (c-M) relation encodes the key information of the assembly history of the dark matter halos, however its behavior at the high mass end has not been measured precisely in observations yet. In this […]
Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Jason T. Hinkle, Thomas W. -S. Holoien, Benjamin. J. Shappee, Jack M. M. Neustadt, Katie Auchettl | Summary: We present observations of ASASSN-20hx, a nearby ambiguous nuclear transient (ANT) discovered in NGC 6297 by the All-Sky Automated Survey for Supernovae (ASAS-SN). We observed ASASSN-20hx from $-$30 to […]

Oren Slone, Fangzhou Jiang, Mariangela Lisanti, Manoj Kaplinghat, | Summary: [[{“value”:”Dark matter self interactions can leave distinctive signatures on the properties of satellite galaxies around Milky Way–like hosts through their impact on tidal stripping, ram pressure, and gravothermal collapse. We delineate the regions of self-interacting dark matter parameter space — specified by interaction cross section […]
