In particular, I am interested in the first phases of galaxy formation and the intergalactic medium. I use deep 2D images and 3D data-cubes of MUSE, Hyper Suprime-Cam and Hubble Space Telescope. For example see ESO's 1738 and 1832 press releases.
With the introduction of the telescope, astronomers have not been using their naked eyes for their professional research any more. Since the introduction of digital detectors and the high processing power of modern computers, today we actually "see" (detect/measure) the heavenly bodies (!) through software, not directly through telescopes any more. Therefore, research in the evolution of galaxies inevitably entails deep involvement in the software that practically define your results. In particular as part of my PhD research in Japan, I developed a new method to detect very diffuse and low surface brightness signal that might have any shape. For an introduction you can see some slides, or a video of my talk in the Indian Institute of Astrophysics (August 2019). The software implementation (NoiseChisel) is released as part of the GNU Astronomy Utilities or Gnuastro.
My research follows an exactly reproducible methodology. To achieve this, I founded Maneage (maneage.org) for easy adoption of any research project which is free software and available to be adopted. For an introduction, see arXiv:2006.03018, some slides, or a video (August 2019).
