100. Early Planet Formation in Embedded Disks in Ophiuchus (eDisk@Oph): Project Overview and Recent Progress

Nagayoshi Ohashi (ASIAA)

5/15/26, 1:45 PM

Oral

As an extension of the ALMA Large Program Early Planet Formation in Embedded Disks (eDisk), we are conducting a survey of a homogeneous sample of 25 protostars in the Ophiuchus star-forming region (eDisk@Oph). The targets were selected from the Spitzer c2d catalog based on their bolometric luminosities and near-infrared spectral indices. The primary scientific objective of this project is to...

43. First High-Resolution ALMA Observations of the Protostellar Jet HH 212 in SiO J = 16–15

YU-SYUAN TU (中研院天文及天文物理研究所(ASIAA))

5/15/26, 2:00 PM

Oral

HH 212 is a nearby protostellar jet driven by the Class 0 protostar IRAS 05413–0104, exhibiting a highly symmetric morphology with well-defined knot structures close to the disk. Previous ALMA observations have mapped HH 212 in the SiO J = 8–7 transition (Band 7). Here, we present the first high-resolution observations of the higher-J transition, SiO J = 16–15 (Band 9).

We find that the...

128. COMPASS - inventory of sulfur-bearing molecules toward BHR71-IRS1

Daniel Harsono

5/15/26, 2:15 PM

Oral

Sulfur is the tenth most abundant element in the universe. It is found in various biomolecules from amino acids to lipids. In space, most of the sulfur is thought to reside on and inside dust grains during the early stages of star and planet formation. Sulfur-bearing molecules have also been detected in comets. To better understand the sulfur trail from diffuse ISM to planet-forming materials,...

130. Physics-Informed Neural Network for Kilonova Light Curves Modeling

Surojit Saha (Institute of Astronomy, National Tsing Hua University, Taiwan)

5/15/26, 2:30 PM

Oral

Physics-informed neural networks (PINNs) have gained considerable importance in recent years in the domain of Astronomy \& Astrophysics, particularly as a potential tool to solve differential equations within the given boundary conditions, not only for making accurate predictions but also for providing an efficient approach for large computations. In this work, we have focused on solving the...

119. A measurement of the Hubble constant with angular cross-correlation between fast radio bursts and galaxies: application to the Second CHIME/FRB Catalog

Tomoki Wada (Tohoku Univ/ NCHU)

5/15/26, 2:45 PM

Oral

The precise measurement of the Hubble constant remains a central challenge in modern cosmology, particularly given the tension between early-universe ( cosmic microwave background) and late-universe ( Type Ia supernovae) measurements. Independent probes are essential for clarifying the origin of this discrepancy. Fast Radio Bursts (FRBs) possess the potential to offer a unique alternative. The...

79. Simulating AGN feedback in galaxy clusters with pre-existing turbulence

Jia-Lun Li (清華大學天文所)

5/15/26, 3:00 PM

Oral

Feedback from active galactic nuclei (AGN) is believed to play a significant role in suppressing cooling flows in cool-core (CC) clusters. Turbulence in the intracluster medium (ICM), which may be induced by AGN activity or pre-existing motions, has been proposed as a potential heating mechanism based on analysis of Chandra X-ray surface brightness fluctuations. However, subsequent simulation...

15. Revealing the Configurations of Near-Resonance Exoplanetary Systems through Long Baseline Transit Timing

Ing-Guey Jiang (National Tsing Hua University)

5/15/26, 3:15 PM

Oral

The possibility that there is a third planet in Kepler-396 system was proposed, but not yet confirmed. In order to investigate this, and understand Kepler-396 system’s configuration, new TESS data are employed to form a long baseline transit timing. Our results support the existence of a third planet. With updated parameters, the planet properties are further investigated. In addition, as...
