Extension of HOPS out to 500 pc (eHOPS). I. Identification and Modeling of Protostars in the Aquila Molecular Clouds
Manoj, P.; Narang, Mayank; Gutermuth, Robert A. +14 more
We present a Spitzer/Herschel focused survey of the Aquila molecular clouds (d ~ 436 pc) as part of the eHOPS (extension of the Herschel orion protostar survey, or HOPS, Out to 500 ParSecs) census of nearby protostars. For every source detected in the Herschel/PACS bands, the eHOPS-Aquila catalog contains 1-850 µm SEDs assembled from the Two…
An R V Map of the Milky Way Revealed by LAMOST
Chen, Bingqiu; Yuan, Haibo; Zhang, Ruoyi
The total-to-selective extinction ratio, R V, is a key parameter for tracing the properties of interstellar dust, as it directly determines the variation of the extinction curve with wavelength. By utilizing accurate color excess measurements from the optical to the mid-infrared range, we have derived R V values for approxima…
The Stellar Abundances and Galactic Evolution Survey (SAGES). I. General Description and the First Data Release (DR1)
Zhao, Gang; Fan, Zhou; Wang, Wei +35 more
The Stellar Abundances and Galactic Evolution Survey (SAGES) of the northern sky is a specifically designed multiband photometric survey aiming to provide reliable stellar parameters with accuracy comparable to those from low-resolution optical spectra. It was carried out with the 2.3 m Bok telescope of Steward Observatory and three other telescop…
A Photometric Survey of Globular Cluster Systems in Brightest Cluster Galaxies
Harris, William E.
Hubble Space Telescope imaging for 26 giant early-type galaxies, all drawn from the MAST archive, is used to carry out photometry of their surrounding globular cluster (GC) systems. Most of these targets are Brightest Cluster Galaxies and their distances range from 24-210 Mpc. The catalogs of photometry, completed with DOLPHOT, are publicly availa…
CLEAR: Survey Overview, Data Analysis, and Products
Papovich, Casey; Finkelstein, Steven L.; Cleri, Nikko J. +19 more
We present an overview of the CANDELS Lyα Emission At Reionization (CLEAR) survey. CLEAR is a 130 orbit program of the Hubble Space Telescope using the Wide Field Camera 3 (WFC3) IR G102 grism. CLEAR targets 12 pointings divided between the GOODS-N and GOODS-S fields of the Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey (CANDELS). Combin…
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Quasar Survey: Quasar Properties from Data Releases 6 to 9
Yao, Su; Jin, Jun-Jie; Wu, Xue-Bing +10 more
We report the fourth installment in the series of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) quasar survey, which includes quasars observed between 2017 September and 2021 June. There are in total 13,066 quasars reliably identified, of which 6685 are newly discovered that are not reported in the Sloan Digital Sky Survey…
The MUSE Ultra Deep Field (MUDF). III. Hubble Space Telescope WFC3 Grism Spectroscopy and Imaging
Papovich, Casey; Henry, Alaina; Rafelski, Marc +18 more
We present extremely deep Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) observations of the MUSE Ultra Deep Field. This unique region of the sky contains two quasars at z ≈ 3.22 that are separated by only ~500 kpc, providing a stereoscopic view of gas and galaxies in emission and absorption across ~10 billion years of cosmic time. We hav…
AutoTAB: Automatic Tracking Algorithm for Bipolar Magnetic Regions
Banerjee, Dipankar; Sreedevi, Anu; Jha, Bibhuti Kumar +1 more
Bipolar magnetic regions (BMRs) provide crucial information about solar magnetism. They exhibit varying morphology and magnetic properties throughout their lifetime, and studying these properties can provide valuable insights into the workings of the solar dynamo. The majority of previous studies have counted every detected BMR as a new one and ha…
A Southern Photometric Quasar Catalog from the Dark Energy Survey Data Release 2
Shen, Yue; Yang, Qian
We present a catalog of 1.4 million photometrically selected quasar candidates in the southern hemisphere over the ~5000 deg2 Dark Energy Survey (DES) wide survey area. We combine optical photometry from the DES second data release (DR2) with available near-infrared (NIR) and the all-sky unWISE mid-infrared photometry in the selection. …
A Systematic Study of Associations between Supernova Remnants and Molecular Clouds
Chen, Zhiwei; Wang, Hongchi; Wang, Min +12 more
We universally search for evidence of kinematic and spatial correlation of supernova remnant (SNR) and molecular cloud (MC) associations for nearly all SNRs in the coverage of the Milky Way Imaging Scroll Painting CO survey, i.e., 149 SNRs, 170 SNR candidates, and 18 pure pulsar wind nebulae in 1° < l < 230° and -5.°5 < b < 5.°5. Based…
