Evolve Vision-Language-Action Model into an Agent with On-the-fly Tool-use
Yi Ding, Yanzhao Yu, Xili Dai +5
This paper integrates end-to-end Visual-Language-Action (VLA) models with agentic tool-use to propose Agentic Robot with Tool-use (ART). ART is a tool-injection framework that tune…
The cosmic ray ionization rate from H3+ observations can be overestimated due to neglect of time-dependent chemistry
Ka Wai Ho, Munan Gong, Kedron Silsbee +1
The cosmic ray ionization rate (CRIR) is a key parameter governing the physical, chemical and thermal evolution of the interstellar medium. The primary technique for measuring the…
modeling of Galactic dust polarized CMB foreground
Alexei G. Kritsuk, Ka Wai Ho, Ka Ho Yuen +1
We present the analysis of high-resolution synthetic dust polarization maps derived from large-scale simulations of magnetized multiphase interstellar turbulence carried out with t…
Statistical signatures of interstellar turbulence in dust polarization maps
Ka Wai Ho, Ka Ho Yuen, Raphael Flauger +1
We present results from a high-resolution interstellar turbulence simulation and show that it closely reproduces recent measurements. Our model captures the scaling of $EE…
The stable "Unstable Natural Media" due to the presence of turbulence
Ka Wai Ho, Ka Ho Yuen, Alex Lazarian
The term "unstable neutral media" (UNM) has traditionally been used to describe the transient phase formed between the warm and cold neutral hydrogen (HI) phases and has not been t…
Tracing magnetic field in super-Alfvenic turbulence with Gradient Technique
Ka Wai Ho, Alex Lazarian
Super-Alfvenic turbulence is important for many astrophysical objects, particularly galaxy clusters. In this paper, we explore the accuracy of Synchrotron Intensity Gradients (SIGs…
