Theoretical Diagnostics for the Physical Conditions in Active Galactic Nuclei under the View of JWST

Posted by klaurent Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Lulu Zhang, Lulu Zhang, , , | Summary: With excellent spectral and angular resolutions and, especially, sensitivity, the JWST allows us to observe infrared emission lines that were previously inaccessible or barely accessible. These emission lines are promising for evaluating the physical conditions in different galaxies. Based […]

Revisiting the Proper Motions of M31 and M33 Using Massive Supergiant Stars with Gaia DR3

Posted by klaurent Peking

Kavli Affiliate: Huawei Zhang | First 5 Authors: Hao Wu, Hao Wu, , , | Summary: The proper motions (PMs) of M31 and M33 are key to understanding the Local Group’s dynamical evolution. However, measurement discrepancies between Gaia blue and red samples, regarding whether the transverse velocity is remarkable, introduce significant ambiguity. In this work, […]
