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: R. Morris | First 5 Authors: A. I. Harris, R. Güsten, M. A. Requena-Torres, D. Riquelme, M. R. Morris | Summary: We report SOFIA-upGREAT spectroscopic imaging of the [C II] 158um spectral line, as well as a number of [O I] 63um spectra, across a 67×45 pc field toward the Sgr B region […]
Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Vadim A. Semenov, Andrey V. Kravtsov, Benedikt Diemer, , | Summary: We compare the performance of energy-based and entropy-conservative schemes for modeling nonthermal energy components, such as unresolved turbulence and cosmic rays, using idealized fluid dynamics tests and isolated galaxy simulations. While both methods are aimed […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Stefan Heimersheim, Nina S. Sartorio, Anastasia Fialkov, Duncan R. Lorimer, | Summary: Fast Radio Bursts (FRBs) are recently-discovered extra-galactic radio transients which exhibit a distance-dependent dispersion of their signal, and thus can be used as cosmological probes. In this article we, for the first time, apply a […]
Kavli Affiliate: Edward H. Morgan | First 5 Authors: Tianjun Gan, Megan Bedell, Sharon Xuesong Wang, Daniel Foreman-Mackey, Jorge Meléndez | Summary: We report the discovery and characterization of a transiting warm sub-Neptune planet around the nearby bright ($V=8.75$ mag, $K=7.15$ mag) solar twin HD 183579, delivered by the Transiting Exoplanet Survey Satellite (TESS). The […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Frank Wilczek, , , , | Summary: I extend, apply, and generalize a model of a quantum radiator proposed by Griffiths to construct models of radiation fields that exhibit high entropy for long periods of time but approach pure states asymptotically. The models, which are fully consistent […]
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: Masahiro Takada | First 5 Authors: Ken Osato, Takahiro Nishimichi, Masahiro Takada, , | Summary: The high-precision measurement of spatial clustering of emission line galaxies (ELGs) is a primary objective for upcoming cosmological spectroscopic surveys. The source of strong emission of ELGs is nebular emission from surrounding ionized gas irradiated by massive short-lived […]
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: Tadayuki Takahashi | First 5 Authors: Tenyo Kawamura, Magnus Axelsson, Chris Done, Tadayuki Takahashi, | Summary: The nature and geometry of the accretion flow in the low/hard state of black hole binaries is currently controversial. While most properties are generally explained in the truncated disc/hot inner flow model, the detection of a broad […]
