Beyond UV: Rest-frame B-band and Apparent Luminosity Functions of z=5-9 Galaxies
Nicha Leethochawalit, Takahiro Morishita, Tirawut Worrakitpoonpon +1
We present new measurements of galaxy luminosity functions (LFs) from JWST/NIRCam imaging over the redshift range z=4.5-9.7, using photometric catalogs from JADES and public extrag…

Extracting the X-ray reverberation response functions from the AGN light curves using an autoencoder
Sanhanat Deesamutara, Poemwai Chainakun, Tirawut Worrakitpoonpon +5
We study the X-ray reverberation in active galactic nuclei (AGN) using the variational autoencoder (VAE), which is a machine-learning algorithm widely used for signal processing an…

Bar instability and formation timescale across Toomre's parameter and central mass concentration: slow bar formation or true stability
Tirawut Worrakitpoonpon
We investigate the bar formation process using -body simulations across the Toomre's parameter and central mass concentration (CMC), focusing principally on the format…
