    A Principle Component Analysis of Galaxy Properties from a Large, Gas-Selected Sample by Yu-Yen Chang, Rikon Chao, Wei-Hao Wang, Pisin Chen

    Published 2012-01-01
    “…In addition, the near-infrared color (i-J) shows an obvious second principal component that might provide evidence of the complex old star formation. Based on our data, we suggest that it is premature to pronounce the failure of the CDM model and it motivates more theoretical work.…”

    Overview of the Near-IR S0 Galaxy Survey (NIRS0S) by E. Laurikainen, H. Salo, R. Buta, J. H. Knapen

    Published 2011-01-01
    “…It was estimated that the spiral bulges brighter than −20 mag in K-band are massive enough to be converted into the bulges of S0s merely by star formation. Bars were found to be fairly robust both in S0s and spirals, but, inspite of that, bars might evolve significantly within the Hubble sequence.…”

    Complex Structure around a Circumstellar Disk Caused by Interchange Instability by Masahiro N. Machida, Shantanu Basu

    Published 2025-01-01
    “…The structures extend to >1000 au and persist for at least 30,000 yr after protostar formation, demonstrating the dynamic removal process of magnetic flux during star formation. We find that the disk continues to grow even as interchange instability occurs, by accretion through channels between the outgoing cavities. …”

    On the Formation of Planets in the Milky Way’s Thick Disk by Tim Hallatt, Eve J. Lee

    Published 2025-01-01
    “…One key difference between the two stellar populations is the time at which they emerged: thick-disk stars are the likely product of cosmic noon (redshift z ∼ 2), an era characterized by high star formation rate, massive and dense molecular clouds, and strong supersonic turbulence. …”

    Published 2025-01-01
    “…Excluding strongly tidal-interacting galaxies, the ratio R _001 / R _1 (anti)correlates strongly and significantly with the H i -to-stellar mass ratio and specific star formation rate, but not with the stellar mass, M _H _i , dark matter mass, or star formation rate. …”

    Implication of Galaxy-scale Negative Feedback by One of the Most Powerful Multiphase Outflows in a Hyperluminous Infrared Galaxy at Intermediate Redshift by Xiaoyang Chen, Masayuki Akiyama, Kohei Ichikawa, Yoshiki Toba, Toshihiro Kawaguchi, Takuma Izumi, Toshiki Saito, Daisuke Iono, Masatoshi Imanishi, Kianhong Lee, Hiroshi Nagai, Hirofumi Noda, Abdurro’uf, Mitsuru Kokubo, Naoki Matsumoto

    Published 2025-01-01
    “…Powerful galactic outflows driven by active galactic nuclei (AGNs) are commonly considered as one of the main mechanisms to regulate star formation in massive galaxies. Ultra- and hyperluminous IR galaxies (U/HyLIRGs) are thought to represent a transition phase of galaxies from a rapidly growing period to a quiescent status as gas is swept out by outflows, providing a laboratory in which to investigate outflows and their feedback effects on hosts. …”

    What Drives the H i Content of Central Galaxies—A Comparison between Hydrodynamic Simulations and Observations Using Random Forest by Xiao Li, Cheng Li, H. J. Mo

    Published 2025-01-01
    “…Beyond that, the accretion rate of supermassive black holes is the most important feature in TNG, while specific star formation rate is the top ranked in EAGLE. This result can be understood from the fact that the H i gas is regulated mainly by thermal-mode AGN feedback in TNG and by stellar feedback in EAGLE. …”
