The narrow-line Seyfert 1 (NLSy1) galaxy, IRAS 17020+4544, is one of the few known sources exhibiting a multi-phase outflow in the highly ionized and molecular phases consistent...

We describe the infrared properties of a large sample of early-type galaxies, comparing data from the Spitzer archive with Ks-band emission from the Two Micron All Sky Survey....

We present the first results of a program to characterize the disk and envelope structure of typical Class 0 protostars in nearby low-mass star-forming regions. We use Spitzer...

We present a high-resolution, multi-wavelength study of the massive protostellar cluster NGC 6334 I(N) that combines new spectral line data from the Submillimeter Array (SMA)...

Infrared Dark Clouds (IRDCs) are dark clouds seen in silhouette in mid-infrared surveys. They are thought to be the birthplace of massive stars, yet remarkably little...

Carbon stars are critical for understanding stellar evolution and exploring cosmic chemistry. This paper provides 7809 carbon star candidates identified from the Large-Area...

We utilized the Edelson & Malkan (2012, J/ApJ/751/52) and Stern+ 2012ApJ...753...30S selection techniques and other methods to identify active galactic nuclei (AGN)...

The evolution of planet-forming disks and the processes of planet formation influence each other, and both of them are possibly impacted by the local environment. Extensive...

We present the survey design and initial results of the Atacama Large Millimeter/submillimeter Array (ALMA) Cycle 9 program of DUALZ, which aims to establish a joint ALMA and...

M dwarf stars are the dominant stellar population in the Milky Way, and they are important for a wide variety of astrophysical topics. The Gaia mission has delivered a superb...

We describe the VISTA Science Archive (VSA) and its first public release of data from five of the six VISTA public surveys. The VSA exists to support the VISTA surveys through...

The full disk, full of gas and dust, determines the upper limit of planet masses, and its lifetime is critical for planet formation, especially for giant planets. In this work,...

We use CEERS JWST/NIRCam imaging to measure rest-frame near-IR light profiles of 435 M>10^10^M_{sun}_ galaxies in the redshift range of 0.5<z<2.3. We compare the...

We performed an HST/WFC3-IR imaging survey of the young stellar cluster NGC 2024 in three filters probing the 1.4{mu}m H2O absorption feature, characteristic of the population...

We analyze 347 galaxies at redshift 4

High-mass prestellar cores are extremely rare. Until recently, the search for such objects has been hampered by small sample sizes, leading to large ambiguities in their...

The ALMA-IMF Large Program imaged 15 massive protoclusters down to a resolution of 2kau scales, identifying about 1000 star-forming cores. The mass and luminosity of these...

We present a comprehensive study of mid-infrared neutral hydrogen (HI) emission lines in 79 nearby (d<200pc) young stars using the James Webb Space Telescope (JWST)...

We study the dust attenuation curves of 230,000 individual galaxies in the local universe, ranging from quiescent to intensely star-forming systems, using GALEX, SDSS, and WISE...

We present a novel multimodal neural network (MNN) for classifying astronomical sources in multiband ground-based observations, from optical to near-infrared (NIR), to separate...
