The Commensal Radio Astronomy FAST Survey (CRAFTS) and its Science Implications

Inspired by the visionary efforts of building Arecibo, the Five-hundred-meter Aperture Spherical radio Telescope (FAST) was formally established as a stand-alone project in 2007.

An interacting view of NGC 1427A

NGC 1427A is a dwarf galaxy located at the outskirts of the Fornax Galaxy Cluster. Its location, shape, and clear star formation events have made this galaxy a nearby laboratory of how dwarfs are affected by the dense environment of the galaxy group. The origin of its star formation burst is unclear: It has been proposed to be due to gravitational interaction (i.e. merger?) or ram pressure stripping. Here I will show, in an interactive way, my latest result of our MUSE integral field observations. I will present the advantages of this analysis approach, drawing my final conclusion about the nature of this galaxy. Finally, if time allows, I would like to present further examples applied to other galaxies as work in progress.

The effect of gravity on light propagation beyond eikonal approximation

Gravity interacts with light by, for instance, curving its trajectory or shifting its frequency. These are the well-known gravitational lensing and cosmological redshift effects. However, on the calculation of such effects it is used the eikonal approximation. This models light as a massless particle travelling in ray paths. When we go beyond that approximation, new effects emerge because the extended (wave) nature of light. In this talk, we will discuss how curved spacetimes can couple to polarization of electromagnetic waves, or even modify its propagation to non-null geodesics.
