The Stellar Initial Mass Function and Population Properties of M89 from Optical and NIR Spectroscopy: Addressing Biases in Spectral Index Analysis

Posted by July 6, 2021Chicago

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Ilaria Lonoce, Anja Feldmeier-Krause, Wendy L. Freedman, , | Summary: The complexity of constraining the stellar initial mass function (IMF) in early-type galaxies cannot be overstated, given the necessity of both very high signal-to-noise (S/N) data and the difficulty of breaking the strong degeneracies that occur […]

A shock near the virial radius of the Perseus Cluster

Posted by klaurent July 4, 2021Stanford

Kavli Affiliate: Steven W. Allen | First 5 Authors: Zhenlin Zhu, Aurora Simionescu, Hiroki Akamatsu, Xiaoyuan Zhang, Jelle S. Kaastra | Summary: Previous X-ray studies of the Perseus Cluster, consisting of 85 Suzaku pointings along eight azimuthal directions, revealed a particularly steep decrease in the projected temperature profile near the virial radius (~r200) towards the […]

To investigate the magnetic-field-induced distortion of NSs through GRB X-ray plateaus

Posted by klaurent July 3, 2021Peking

Kavli Affiliate: Renxin Xu | First 5 Authors: Tingting Lin, Shuang Du, Renxin Xu, , | Summary: Magnetic field may distort neutron stars (NSs), but the effect has not been robustly tested through gravitational-wave observation yet due to the absence of a fast rotating Galactic magnetar. The central objects of Gamma-ray bursts (GRBs) could be […]

Tunable strong coupling of mechanical resonance between spatially separated FePS$_3$ nanodrums

Posted by klaurent July 2, 2021Delft

Kavli Affiliate: Herre S. J. Van Der Zant | First 5 Authors: Makars Šiškins, Ekaterina Sokolovskaya, Martin Lee, Samuel Mañas-Valero, Dejan Davidovikj | Summary: Coupled nanomechanical resonators made of two-dimensional materials are promising for processing information with mechanical modes. However, the challenge for these types of systems is to control the coupling. Here, we demonstrate […]

Lattice Renormalization of Quantum Simulations

Posted by klaurent July 2, 2021Chicago

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Henry Lamm, Ying-Ying Li, Wanqiang Liu, | Summary: With advances in quantum computing, new opportunities arise to tackle challenging calculations in quantum field theory. We show that trotterized time-evolution operators can be related by analytic continuation to the Euclidean transfer matrix on an anisotropic lattice. […]

Posted by klaurent July 2, 2021Stanford

Kavli Affiliate: R. Morris | First 5 Authors: R. Abuter, A. Amorim, M. Bauböck, F. Baganoff, J. P. Berge | Summary: We report the time-resolved spectral analysis of a bright near-infrared and moderate X-ray flare of Sgr A*. We obtained light curves in the $M$-, $K$-, and $H$-bands in the mid- and near-infrared and in […]
