While cloud-cloud collisions (CCCs) have been proposed as a mechanism for triggering massive star formation, it is suggested that higher collision velocities ($v_{\rm col}$) and lower GMC mass ($M_{\rm GMC}$) or/and density ($\Sigma_{\rm tend to suppress formation.

Abstract While cloud–cloud collisions (CCCs) have been proposed as a mechanism for triggering massive star formation, it is suggested that higher collision velocities ( v col ) and lower giant molecular cloud (GMC) mass M GMC and/or density (Σ tend to suppress formation.

Abstract The tip of the tidal tail, resulting from an encounter between galaxies, features gas concentrations and some star-forming regions, such as dwarf galaxies (TDGs). This region provides a unique laboratory for examining star formation process in dynamical environment distinct that disk galaxies. Using Nobeyama 45 m telescope, we conducted 12 CO(1−0) position-switching observations at tips southern tail Antennae We detected CO emission not only two TDG candidates but also regions with...
Abstract We study the major merger fraction along massive galaxy-quenching channel (traced with rest-frame $\mathrm{NUV}-r$ color) at z = 0.2–0.7, aiming to examine cosmic web detachment (CWD) scenario of galaxy quenching. In this scenario, is expected be high in green-valley galaxies as compared those star-forming and quiescent similar stellar mass. used photometry E-COSMOS field select 1491 (2334) ($M_\ast \\gt 10^{9.5}\, M_{\odot }$) $m_i\\lt 22$ mag ($m_z\\lt mag) 0.2–0.4 (z 0.4–0.7)...
