Close Major-merger Pairs at z = 0: Star-forming Galaxies with Pseudobulges

Wang, Wei; Xu, Cong; Fang, Taotao +5 more

We present a study of star-forming galaxies (SFGs) with pseudobulges (bulges with Sérsic index n < 2) in a local close major-merger galaxy pair sample (H-KPAIR). With data from new aperture photometries in the optical and near-infrared bands (aperture size of 7 kpc) and from the literature, we find that the mean Age of central stellar populatio…

A Catalog of ¹³CO Clumps from the MWISP in l = 10°–20°

Chen, Zhiwei; Jiang, Zhibo; Zeng, Xiangyun +8 more

In this study, we present a catalog of molecular clumps extracted from ¹³CO (J = 1 ‑ 0) emission data of the Milky Way Imaging Scroll Painting (MWISP) project. The data covers the inner Milky Way within the longitude range 10° ≤ l ≤ 20° and the latitude strip of ∣b∣ ≤ 5.°25. The workflow for the extraction of clumps, namely Facet-SS-3D-…
