Multiwavelength Bulge-Disk Decomposition for the Galaxy M81 (NGC 3031). I. Morphology
Jun-Yu Gong, Ye-Wei Mao, Hua Gao +1
A panchromatic investigation of morphology for the early-type spiral galaxy M81 is presented in this paper. We perform bulge-disk decomposition in M81 images at a total of 20 waveb…
Redshifting galaxies from DESI to JWST CEERS: Correction of biases and uncertainties in quantifying morphology
Si-Yue Yu, Cheng Cheng, Yue Pan +2
Observations of high-redshift galaxies with unprecedented detail have now been rendered possible with JWST. However, accurately quantifying their morphology remains uncertain due t…
Born this way: thin disc, thick disc, and isotropic spheroid formation in FIRE-2 Milky-Way-mass galaxy simulations
Sijie Yu, James S. Bullock, Alexander B. Gurvich +7
We investigate the formation of Milky-Way-mass galaxies using FIRE-2 LCDM cosmological zoom-in simulations by studying the orbital evolution of stars formed in the main progenitor…
The EDGE-CALIFA survey: The role of spiral arms and bars in driving central molecular gas concentrations
Si-Yue Yu, Veselina Kalinova, Dario Colombo +9
Shocks and torques produced by non-axisymmetric structures such as spiral arms and bars may transport gas to galaxy central regions. We test this hypothesis by studying the depende…
Strong spiral arms drive secular growth of pseudo bulges in disk galaxies
Si-Yue Yu, Dewang Xu, Luis C. Ho +2
Spiral-driven instabilities may drive gas inflow to enhance central star formation in disk galaxies. We investigate this hypothesis using the Sloan Digital Sky Survey (SDSS) in a s…
Galaxies lacking dark matter produced by close encounters in a cosmological simulation
Jorge Moreno, Shany Danieli, James S. Bullock +18
The standard cold dark matter plus cosmological constant model predicts that galaxies form within dark-matter haloes, and that low-mass galaxies are more dark-matter dominated than…
