Height-Dependent LoS Probability Model for A2G MmWave Communications under Built-up Scenarios

Kavli Affiliate: Zhuo Li | First 5 Authors: Minghui Pang, Qiuming Zhu, Fei Bai, Zhuo Li, Hanpeng Li | Summary: Based on the three-dimensional propagation characteristic under built-up scenarios, a height-dependent line-of-sight (LoS) probability model for air-to-ground (A2G) millimeter wave (mmWave) communications is proposed in this paper. With comprehensive considerations of scenario factors, i.e., building […]

Neutron Star$-$Neutron Star and Neutron Star$-$Black Hole Mergers: Multiband Observations and Early Warnings

Kavli Affiliate: Lijing Shao | First 5 Authors: Chang Liu, Lijing Shao, , , | Summary: The detections of gravitational waves (GWs) from binary neutron star (BNS) systems and neutron star–black hole (NSBH) systems provide new insights into dense matter properties in extreme conditions and associated high-energy astrophysical processes. However, currently information about NS equation […]

Detection of H$_2$ in the TWA 7 System: A Probable Circumstellar Origin

Kavli Affiliate: Gregory Herczeg | First 5 Authors: Laura Flagg, Christopher Johns-Krull, Kevin France, Gregory Herczeg, Joan Najita | Summary: Using HST-COS FUV spectra, we have discovered warm molecular hydrogen in the TWA 7 system. TWA 7, a $sim$9 Myr old M2.5 star, has a cold debris disk and has previously shown no signs of […]

The miniJPAS Survey: A Study on Wavelength Dependence of the Photon Response Non-uniformity of the JPAS-{it Pathfinder} Camera

Kavli Affiliate: Hu Zhan | First 5 Authors: Kai Xiao, Haibo Yuan, J. Varela, Hu Zhan, Jifeng Liu | Summary: Understanding the origins of small-scale flats of CCDs and their wavelength-dependent variations plays an important role in high-precision photometric, astrometric, and shape measurements of astronomical objects. Based on the unique flat data of 47 narrow-band […]

Exploring a PMT+SiPM Hybrid Optical Module for Next Generation Neutrino Telescopes

Kavli Affiliate: Zhuo Li | First 5 Authors: Fan Hu, Zhuo Li, Donglian Xu, , | Summary: Cosmic neutrinos are unique probes of the high energy universe. IceCube has discovered a diffuse astrophysical neutrino flux since 2013, but their origin remains elusive. The potential sources could include, for example, active galactic nuclei, gamma-ray bursts and […]

Dynamics and Morphology of Cold Gas in Fast, Radiatively Cooling Outflows: Constraining AGN Energetics with Horseshoes

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 […]

Orbital Evolution of Satellite Galaxies in Self-Interacting Dark Matter Models

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 […]
