    Progenitor Diversity in the Accreted Stellar Halos of Milky Way–like Galaxies by Sy-Yun Pu, Andrew P. Cooper, Robert J. J. Grand, Facundo A. Gómez, Antonela Monachesi

    Published 2025-01-01
    “…Predictions of diversity from numerical simulations are sensitive to model-dependent assumptions regarding the efficiency of star formation in dwarf galaxies. We compare, at face value, to current constraints on the radial diversity of the Milky Way's accreted halo. …”

    MUSEQuBES: Unveiling Cosmic Web Filaments at z ≈ 3.6 through Dual Absorption and Emission Line Analysis by Eshita Banerjee, Sowgat Muzahid, Joop Schaye, Sebastiano Cantalupo, Sean D. Johnson

    Published 2025-01-01
    “…According to modern cosmological models, galaxies are embedded within cosmic filaments, which supply a continuous flow of pristine gas, fueling star formation and driving their evolution. However, due to their low density, the direct detection of diffuse gas in cosmic filaments remains elusive. …”

    The Age–Velocity Dispersion Relations of the Galactic Disk as Revealed by the LAMOST-Gaia Red Clump Stars by Weixiang Sun, Han Shen, Biwei Jiang, Xiaowei Liu

    Published 2025-01-01
    “…These results indicate that the thin disk stars are likely heated by long-term heating from giant molecular clouds and spiral arms, while thick disk stars are likely heated by some violent heating process from merger and accretion, and/or formed by the inside-out and upside-down star formation scenarios, and/or born in the chaotic mergers of gas-rich systems and/or turbulent interstellar medium. …”

    Spin-down of Solar-mass Protostars in Magnetospheric Accretion Paradigm by Shinsuke Takasao, Masanobu Kunitomo, Takeru K. Suzuki, Kazunari Iwasaki, Kengo Tomida

    Published 2025-01-01
    “…Nevertheless, stellar spin-down mechanisms in protostellar and pre-main-sequence stellar phases have been a long-standing problem in star formation theory. To realize the spin-down, previous axisymmetric models based on the conventional magnetospheric paradigm have had to assume massive stellar winds or produce highly time-variable magnetospheric ejections. …”

    Published 2025-01-01
    “…First, the host star's spin becomes misaligned with the planetary disk during the late stages of star formation, primarily due to chaotic accretion and magnetic interactions between the star and the planetary disk. …”

    Published 2025-01-01
    “…J1205–0000 has a high FIR luminosity, L _FIR  = 2.5 × 10 ^12 L _⊙ and a total IR luminosity of L _TIR  = 3.5 × 10 ^12 L _⊙ , corresponding to a star formation rate of  ∼528 M _⊙ yr ^−1 . With the [C  ii ]-based dynamical mass of  ∼1 × 10 ^11 M _⊙ , we conclude that J1205–0000 is hosted by a starburst galaxy. …”

    ALMA/SCUBA-2 COSMOS Survey: Properties of X-Ray- and SED-selected Active Galactic Nuclei in Bright Submillimeter Galaxies by Ryosuke Uematsu, Yoshihiro Ueda, David M. Alexander, A. M. Swinbank, Ian Smail, Carolina Andonie, Chian-Chou Chen, Ugne Dudzevičiūtė, Soh Ikarashi, Kotaro Kohno, Yuichi Matsuda, Annagrazia Puglisi, Hideki Umehata, Wei-Hao Wang

    Published 2025-01-01
    “…This fraction is almost consistent with the general galaxy population at z  ∼ 2, suggesting that major mergers are not necessarily required for the enhanced star formation in SMGs. We also identify $4{7}_{-15}^{+16}$ % of the AGN hosts as major merger candidates, which is about twice as high as that in the SMGs without AGNs. …”

    JWST, ALMA, and Keck Spectroscopic Constraints on the UV Luminosity Functions at z ∼ 7–14: Clumpiness and Compactness of the Brightest Galaxies in the Early Universe by Yuichi Harikane, Akio K. Inoue, Richard S. Ellis, Masami Ouchi, Yurina Nakazato, Naoki Yoshida, Yoshiaki Ono, Fengwu Sun, Riku A. Sato, Giovanni Ferrami, Seiji Fujimoto, Nobunari Kashikawa, Derek J. McLeod, Pablo G.

Koekemoer, Nicolas Laporte, Chien-Hsiu Lee, Dan Magee, Hiroshi Matsuo, Yoshiki Matsuoka, Ken Mawatari, Kimihiko Nakajima, Minami Nakane, Yoichi Tamura, Hiroya Umeda, Hiroto Yanagisawa

    Published 2025-01-01
    “…We find that ∼70% of the bright galaxies at z ∼ 7 exhibit clumpy morphologies with multiple subcomponents, suggesting merger-induced starburst activity, which is consistent with SED fitting results showing bursty star formation histories. At z ≳ 10, bright galaxies are classified into two types of galaxies: extended ones with weak high-ionization emission lines, and compact ones with strong high-ionization lines including N iv] λ 1486, indicating that at least two different processes (e.g., merger-induced starburst and compact star formation/AGN) are shaping the physical properties of the brightest galaxies at z ≳ 10 and are responsible for their overabundance.…”

    Published 2025-02-01
    “…Here we present a plan for observing the Galactic Plane and circumstellar environments to quantify the physical structure, the magnetic fields, the dynamics, chemistry, star formation, and planetary system evolution of the galaxy in which we live with AtLAST; a concept for a new, 50m single-dish sub-mm telescope with a large field of view which is the only type of facility that will allow us to observe our Galaxy deeply and widely enough to make a leap forward in our understanding of our local ecology.…”
