Kavli Affiliate: Debora Sijacki | First 5 Authors: Colin DeGraf, Debora Sijacki, Tiziana Di Matteo, Kelly Holley-Bockelmann, Greg Snyder | Summary: With projects such as Laser Interferometer Space Antenna (LISA) and Pulsar Timing Arrays expected to detect gravitational waves from supermassive black hole mergers in the near future, it is key that we understand what […]
Kavli Affiliate: Chiaki Hikage | First 5 Authors: Takahiko Matsubara, Chiaki Hikage, Satoshi Kuriki, , | Summary: The second-order formula of Minkowski functionals in weakly non-Gaussian fields is compared with the numerical $N$-body simulations. Recently, weakly non-Gaussian formula of Minkowski functionals is extended to include the second-order effects of non-Gaussianity in general dimensions. We apply […]
Kavli Affiliate: David A. Principe | First 5 Authors: Lucas A. Cieza, Camilo González-Ruilova, Antonio S. Hales, Paola Pinilla, Dary Ruíz-Rodríguez | Summary: We present 1.3 mm continuum ALMA long-baseline observations at 3-5 au resolution of 10 of the brightest discs from the Ophiuchus DIsc Survey Employing ALMA (ODISEA) project. We identify a total of […]
Kavli Affiliate: Naoki Yasuda | First 5 Authors: Takashi J. Moriya, Ji-an Jiang, Naoki Yasuda, Mitsuru Kokubo, Kojiro Kawana | Summary: Some supernovae such as pair-instability supernovae are predicted to have the duration of more than a year in the observer frame. To constrain the rates of supernovae lasting for more than a year, we […]
Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Yuhan Yao, S. R. Kulkarni, K. C. Gendreau, Gaurava K. Jaisawal, Teruaki Enoto | Summary: Here, we present MAXI, SWIFT, NICER, NuSTAR and Chandra observations of the X-ray transient AT2019wey (SRGA J043520.9+552226, SRGE J043523.3+552234). From spectral and timing analyses we classify it as a Galactic low-mass […]
Kavli Affiliate: Eli Rykoff | First 5 Authors: Valtteri Lindholm, Alexis Finoguenov, Johan Comparat, Charles C. Kirkpatrick, Eli Rykoff | Summary: Aims. We analyze the autocorrelation function of a large contiguous sample of galaxy clusters, the Constrain Dark Energy with X-ray (CODEX) sample, in which we take particular care of cluster definition. These clusters were […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Martijn de Vries, Roger W. Romani, Oleg Kargaltsev, George Pavlov, Bettina Posselt | Summary: We have obtained a deep 670 ks CXO ACIS image of the remarkable pulsar wind nebula (PWN) of PSR J1709-4429, in 4 epochs during 2018-2019. Comparison with an archival 2004 data set […]
Kavli Affiliate: Philip J. Marshall | First 5 Authors: Ji Won Park, Sebastian Wagner-Carena, Simon Birrer, Philip J. Marshall, Joshua Yao-Yu Lin | Summary: We investigate the use of approximate Bayesian neural networks (BNNs) in modeling hundreds of time-delay gravitational lenses for Hubble constant ($H_0$) determination. Our BNN was trained on synthetic HST-quality images of […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Qi Shu, Xiaoying Pang, Francesco Flammini Dotti, M. B. N. Kouwenhoven, Manuel Arca Sedda | Summary: We present a comprehensive investigation of main-sequence (MS) binaries in the DRAGON simulations, which are the first one-million particles direct $N$-body simulations of globular clusters. We analyse the orbital parameters of […]
Kavli Affiliate: Ralf K. Heilmann | First 5 Authors: Hans Moritz Günther, Ralf K. Heilmann, , , | Summary: Lynx is one of four large-mission concept studies for NASA’s 2020 Decadal survey. The design reference mission includes an X-ray grating spectrometer (XGS) based on critical-angle transmission (CAT) gratings. In the past we studied different grating […]
