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: 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 […]
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 […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Ichikawa, Takuji Yamashita, Yoshiki Toba, Tohru Nagao, Kohei Inayoshi | Summary: We present the optical and infrared properties of 39 extremely radio-loud galaxies discovered by cross-matching the Subaru/Hyper Suprime-Cam (HSC) deep optical imaging survey and VLA/FIRST 1.4 GHz radio survey. The recent Subaru/HSC strategic survey revealed […]
Kavli Affiliate: Kejia Lee | First 5 Authors: Shivani Bhandari, Kasper E. Heintz, Kshitij Aggarwal, Lachlan Marnoch, Cherie K. Day | Summary: We present the localization and host galaxies of one repeating and two apparently non-repeating Fast Radio Bursts. FRB20180301A was detected and localized with the Karl G. Jansky Very Large Array to a star-forming […]
Kavli Affiliate: Xian Chen | First 5 Authors: Verónica Vázquez-Aceves, Lorenz Zwick, Elisa Bortolas, Pedro R. Capelo, Pau Amaro-Seoane | Summary: One of the main targets of the Laser Interferometer Space Antenna (LISA) is the detection of extreme mass-ratio inspirals (EMRIs) and extremely large mass-ratio inspirals (X-MRIs). Their orbits are expected to be highly eccentric […]
Kavli Affiliate: Huawei Zhang | First 5 Authors: Xiao-Wei Duan, Xiaodian Chen, Weijia Sun, Licai Deng, Huawei Zhang | Summary: Hydrogen emissions of RR Lyrae variables are the imprints of shock waves traveling through their atmospheres. We develop a pattern recognition algorithm, which is then applied to single-epoch spectra of SDSS and LAMOST. These two […]
Kavli Affiliate: Ran Wang | First 5 Authors: Tomonari Michiyama, Toshiki Saito, Ken-ichi Tadaki, Junko Ueda, Ming-Yang Zhuang | Summary: We present the results of surveying [CI] $^3P_1-^3P_0$, $^{12}$CO $J=4-3$, and 630 $mu$m dust continuum emission for 36 nearby ultra/luminous infrared galaxies (U/LIRGs) using the Band 8 receiver mounted on the Atacama Compact Array (ACA) […]
Kavli Affiliate: Huawei Zhang | First 5 Authors: Fangfei Shi, Donald W. Kurtz, Daniel L. Holdsworth, Hideyuki Saio, Margarida S. Cunha | Summary: We report the frequency analysis of a known roAp star, HD 86181 (TIC 469246567), with new inferences from TESS data. We derive the rotation frequency to be $nu_{rot}$ = 0.48753 $pm$ 0.00001d$^{-1}$. […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Ziyan Xu, Gregory J. Herczeg, Christopher M. Johns-Krull, Kevin France, | Summary: We present an analysis of wind absorption in the C II ${lambda}1335$ doublet towards 40 classical T Tauri stars with archival far-ultraviolet (FUV) spectra obtained by the Hubble Space Telescope. Absorption features produced by […]
