J-PAS: unprecedented precision in stellar populations of diffuse tidal features

Sepideh Eskandarlou, Mohammad Akhlaghi, Francisco Arizo-Borillo +38

Galaxies frequently interact with nearby systems, a process that can significantly alter their morphology and star formation activity. However, spectroscopic studies of their faint…

J-PLUS: Turning Off the Bright Stars

Sepideh Eskandarlou, Mohammad Akhlaghi, Johan H. Knapen +23

Photometric surveys require precise point spread function (PSF) characterization, as it varies across filters and is crucial for accurate photometry and low surface brightness (LSB…

Extragalactic Stellar Tidal Streams: Observations meet Simulation

Juan Miro-Carretero, Maria A. Gomez-Flechoso, David Martinez-Delgado +11

According to the well established hierarchical framework for galaxy evolution, galaxies grow through mergers with other galaxies and the LambdaCDM cosmological model predicts that…
