Overview

Ivan Valtchanov is affiliated with the European Space Astronomy Centre in Spain. Their scientific contributions primarily lie within the field of Physics and Astronomy, where they have published extensively in subfields such as Astronomy and Astrophysics, Instrumentation, Computational Mechanics, Computer Vision and Pattern Recognition, and Atomic and Molecular Physics, and Optics. Their research topics encompass areas related to Galaxies: Formation, Evolution, Phenomena, Astrophysics and Star Formation Studies, Astrophysical Phenomena and Observations, Stellar, planetary, and galactic studies, Astronomy and Astrophysical Research, Astronomical Observations and Instrumentation, and Atmospheric Ozone and Climate.

Valtchanov has contributed multiple papers focused on astronomical imaging and astrophysical phenomena. Recent publications include:

  • Learning to denoise astronomical images with U-nets, 2020, Monthly Notices of the Royal Astronomical Society
  • Ionized emission and absorption in a large sample of ultraluminous X-ray sources, 2021, Monthly Notices of the Royal Astronomical Society
  • Deep learning-based super-resolution and de-noising for XMM-newton images, 2022, Monthly Notices of the Royal Astronomical Society
  • Resolved Neutral Outflow from a Lensed Dusty Star-forming Galaxy at z = 2.09, 2021, HAL (Le Centre pour la Communication Scientifique Directe)
  • A high redshift population of galaxies at the North Ecliptic Pole, 2020, Astronomy and Astrophysics

The frequent venues where Ivan Valtchanov's work appears include:

  • Monthly Notices of the Royal Astronomical Society
  • Astronomy and Astrophysics
  • arXiv (Cornell University)
  • Zenodo (CERN European Organization for Nuclear Research)
  • HAL (Le Centre pour la Communication Scientifique Directe)

Collaboration is evident in Valtchanov's research, with repeated co-authorship alongside several scientists, notably:
