Probing Diversity of Type II Supernovae with the Chinese Space Station Telescope
Universe, 2023 Type II supernovae (SNe II), which show abundant hydrogen in their spectra, belong to a class of SNe with diverse observed properties. It is commonly accepted that SNe II are produced by core collapse and explosion of massive stars.

The Australia Telescope National Facility Pulsar Catalogue [PDF]
, 2003 We have compiled a new and complete catalog of the main properties of the 1509 pulsars for which published information currently exists. The catalog includes all spin-powered pulsars, as well as anomalous X-ray pulsars and soft gamma-ray repeaters ...

Science case for the Einstein telescope [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 The Einstein Telescope (ET), a proposed European ground-based gravitational-wave detector of third-generation, is an evolution of second-generation detectors such as Advanced LIGO, Advanced Virgo, and KAGRA which could be operating in the mid 2030s.

Black holes with scalar hair in light of the Event Horizon Telescope [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Searching for violations of the no-hair theorem (NHT) is a powerful way to test gravity, and more generally fundamental physics, particularly with regards to the existence of additional scalar fields.

Temporal Variations of the Turbulence Profiles at the Sayan Solar Observatory Site
Atmosphere, 2019 The paper focuses on the development of the method to estimate the mean characteristics of the atmospheric turbulence. Using an approach based on the shape of the energy spectrum of atmospheric turbulence over a wide range of spatial and temporal scales,

Freeform Wide Field-of-View Spaceborne Imaging Telescope: From Design to Demonstrator
Sensors, 2022 Wide field-of-view imaging optics offer a huge potential for space-based Earth observation enabling the capture of global data. Reflective imaging telescopes are often favored, as they do not show chromatic aberrations and are less susceptible to ...

Active optics: deformable mirrors with a minimum number of actuators [PDF]
Journal of the European Optical Society-Rapid Publications, 2012 We present two concepts of deformable mirror to compensate for first order optical aberrations. Deformation systems are designed using both elasticity theory and Finite Element Analysis in order to minimize the number of actuators.
