Kavli Affiliate: Jing Wang | First 5 Authors: Dongheng Qian, Jing Wang, , , | Summary: Measurement-induced phase transition (MIPT) is a novel non-equilibrium phase transition characterized by entanglement entropy. The scrambling dynamics induced by random unitary gates can protect information from low-rate measurements. However, common decoherence noises, such as dephasing, are detrimental to the […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Wen-Yong Kang, Jun-Xian Wang, Zhen-Yi Cai, Hao-Chen Wang, Wen-Ke Ren | Summary: Quasars are generally divided into jetted radio-loud and non-jetted radio-quiet ones, but why only 10% quasars are radio loud has been puzzling for decades. Other than jet-induced-phenomena, black hole mass, or Eddington ratio, prominent difference […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Matthew J. Temple, Amy L. Rankine, Manda Banerji, Joseph F. Hennawi, Paul C. Hewett | Summary: Understanding the links between different phases of outflows from active galactic nuclei is a key goal in extragalactic astrophysics. Here we compare [OIII] $lambdalambda$4960,5008 outflow signatures in quasars with and without […]
Kavli Affiliate: Yingjie Peng | First 5 Authors: Enci Wang, Jianhui Lian, Yingjie Peng, Xin Wang, | Summary: Both simulations and observations suggest that the disk assembly of galaxies is governed by the interplay between coplanar gas inflow, ex-planar gas outflow and in-situ star formation on the disk, known as the leaky accretion disk. This […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Zhen Cao, F. Aharonian, Q. An, Axikegu, Y. X. Bai | Summary: In this work we try to search for signals generated by ultra-heavy dark matter at the Large High Altitude Air Shower Observatory (LHAASO) data. We look for possible gamma-ray by dark matter annihilation or […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Zhen Cao, F. Aharonian, Q. An, Axikegu, Y. X. Bai | Summary: In this work we try to search for signals generated by ultra-heavy dark matter at the Large High Altitude Air Shower Observatory (LHAASO) data. We look for possible gamma-ray by dark matter annihilation or decay […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Robert Wheatley, Catherine J. Grier, Patrick B. Hall, W. N. Brandt, Jonah Lotz | Summary: We present the results of an investigation of a highly variable CIV broad absorption-line feature in the quasar SBS 1408+544 (z=2.337) that shows a significant shift in velocity over time. This source […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Minjin Kim, Suyeon Son, Luis C. Ho, , | Summary: We investigate the optical variability of low-redshift ($0.15< zleq0.4$) active galactic nuclei using the multi-epoch data from the Zwicky Transient Facility. We find that a damped random walk model well describes the ensemble structure function in […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Boy Lankhaar, Susanne Aalto, Clare Wethers, Javier Moldon, Rob Beswick | Summary: High resolution (0."037-0."13 [10-35 pc]) e-MERLIN ($lambda6-18$ cm) and (0."024 [6.5 pc]) ALMA ($lambda 1.1$ mm) observations have been used to image OH (hydroxyl) and H$_2$CO (formaldehyde) megamaser emission, and HCN 3->2 emission towards the […]
