A Study of the Star Clusters’ Population in the Giant Molecular Cloud G174+2.5 by Tatyana A. Permyakova, Giovanni Carraro, Anton F. Seleznev, Andrej M. Sobolev, Dmitry A. Ladeyschikov, Maria S. Kirsanova

“…We study the structure, interstellar absorption, color–magnitude diagrams (CMDs), kinematics, and dynamical state of embedded star clusters in the star-forming region associated with the giant molecular cloud G174+2.5. Our investigation is based on photometric data from the UKIDSS Galactic Plane Survey catalog and astrometric data from the Gaia DR3 catalogs. …”

An In-depth Investigation of the Primordial Cluster Pair ASCC 19 and ASCC 21 by Qingshun Hu, Yuting Li, Mingfeng Qin, Chenglong Lv, Yang Pan, Yangping Luo, Shuo Ma

“…These similarities suggest that the clusters likely originated from the fragmentation of the same molecular cloud, forming a primordial cluster pair. Furthermore, the formation of the two clusters is attributed to the coalescence of multiple subclusters, as inferred from the distribution analysis between metal abundances and distances to clusters’ centers. …”

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

“…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. Solving for the background radiation field in these early star-forming regions, we demonstrate that protoplanetary disks at cosmic noon experienced radiation fields up to ∼7 orders of magnitude more intense than in solar neighborhood conditions. …”

Dark Galactic Subhalos and the Gaia Snail by Daniel Gilman, Jo Bovy, Neige Frankel, Andrew Benson

“…We also develop a phenomenological treatment for the diffusion of phase-space spirals caused by gravitational scattering between stars and giant molecular clouds, a process that erases the kinematic signatures of old ( t  ≳ 0.6 Gyr) events. …”

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

“…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. …”

Atacama Large Aperture Submillimeter Telescope (AtLAST) science: Our Galaxy [version 2; peer review: 2 approved] by Pamela Klaassen, Maria Beltrán, Alessio Traficante, Mark Booth, Kate Pattle, Jonathan Marshall, Joshua Lovell, Brandt Gaches, Alvaro Hacar, Nicolas Peretto, Caroline Bot, Doris Arzoumanian, Thomas Stanke, Gaspard Duchêne, Ana Duarte Cabral, Antonio Hales, David Eden, Patricia Luppe, Jens Kauffmann, Elena Redaelli, Sebastian Marino, Álvaro Sánchez-Monge, Andrew Rigby, Dmitry Semenov, Eugenio Schisano, Mark Thompson, Silvia Spezzano, Claudia Cicone, Friedrich Wyrowski, Martin Cordiner, Tony Mroczkowski, Doug Johnstone, Luca Di Mascolo, Minju Lee, Eelco van Kampen, Thomas Maccarone, Daizhong Liu, Matthew Smith, Amélie Saintonge, Sven Wedemeyer, Alexander Thelen

“…As we learn more about the multi-scale interstellar medium (ISM) of our Galaxy, we develop a greater understanding for the complex relationships between the large-scale diffuse gas and dust in Giant Molecular Clouds (GMCs), how it moves, how it is affected by the nearby massive stars, and which portions of those GMCs eventually collapse into star forming regions. …”

Pushing the Atacama Large Millimeter/submillimeter Array to the Limit: 140 pc Resolution Observations of a z = 6.6 Quasar–Galaxy Merger Resolve Strikingly Different Morphologies of... by Romain A. Meyer, Bram Venemans, Marcel Neeleman, Roberto Decarli, Fabian Walter

“…The absence of significant [C ii ] emission by structures with physical scale ≲ 1 kpc implies that [C ii ] emission is not produced in dense PDRs located at the boundary of giant molecular clouds. We argue instead that [C ii ] is produced in low-density PDRs in the interstellar medium and diffuse H i gas tidally stripped during the ongoing merger.…”
