The Quenching of Star Formation in Galaxy Clusters since z~1
Abstract

I will present an analysis of the quenching of star formation (SF) in galaxy clusters since z~1, based on a sample of 220 galaxy clusters from the SpARCS survey in the XMM-LSS and ELAIS-N1 fields, using the public data release from HSC-SSP and Sptizer SWIRE survey data in these fields. In particular, we examine the star-forming galaxy fraction (f_SF) as a function of redshift, galaxy stellar mass, and cluster-centric radius. I will also present some preliminary results on the SFR-stellar mass relation (the "main sequence") in the field and in clusters, using a combination of HSC and Spitzer SWIRE MIPS data, over the same redshift range.

Multi-wavelength polarization observation toward the filamentary cloud IC5146
Abstract

Whether magnetic fields are important in the star formation is a fundamental question in astrophysics. The studies in past decades show that the role of magnetic fields in star formation is complicated and diverse, and that neither of the two extreme case theories (dominating or negligible magnetic fields) can fully explain the star formation activity. Hence, the detailed investigations of the role of magnetic fields in particular physical scale, density, and environments are necessary to reveal the full picture, which thus requires multi-wavelength observations to trace. In this talk, I would present our polarization observations in optical, infrared, and submillimeter wavelengths toward the filamentary clouds IC5146. I would first discuss how deep we can trace using each data set, and further show how the role of magnetic fields possibly change in different scale.

Mass Discrepancy-Acceleration Relation in Dark Matter Problem
Abstract

Mass discrepancy-acceleration relation (MDAR) is a relation in dark matter problem found in spiral galaxies. The mass ratio between observational mass divided by baryonic mass strongly related to baryonic acceleration (or observational acceleration) but unrelated to other physical quantities (ex, radius). Recently, McGaugh et al. 2016 (PRL117.201101) revealed a tight relation between observational acceleration and baryonic acceleration in 153 spiral galaxies from SPARC database which is consistent to the MDAR. It can well explain Tully-Fisher relation, deficient dark matter in ordinary elliptical galaxies, surface densities discrepancy etc. However, our work focus (Tian & Ko 2017) on elliptical galaxies in strong lensing such as Einstein rings. We found the MDAR in 57 elliptical lenses is consistent with spiral galaxies.

Dependence of Global and Spatially-resolved SFR-M* Relations on Galaxy Properties
Abstract

The galaxy integrated star formation rate(SFR)-stellar mass(M∗) relation holds important information for understanding the star formation history and evolution of galaxies. Although the SFR-M∗ relation has been reported with a variety of different data sets, their appearance can vary significantly from one to another. In this work, we determine what controls the integrated and the spatially-resolved SFR-M* relation in both star-forming and quiescent galaxies by linking the spatially resolved SFR-M* relation with various galaxy properties such as stellar mass and bulge-to-total light ratio using MaNGA data (Mapping Nearby Galaxies at APO).
