This work is to retrieve emission-line spectra from the "Unknown" data set in LAMOST DR7 V1.2, most of which are low signal-to-noise ratios spectra. In the work, we perform...

We present an analysis of the metallicity and star formation activities of HII regions in the interacting system Arp 86, based on the first scientific observations using...

As the recent publication by Breen et al. (2013MNRAS.435..524B) found, Class II methanol masers are exclusively associated with high mass star forming regions. Based on the...

The galaxy NGC6384 has been observed with an IPCS through H{alpha} and [NII] narrow-band interference filters for direct imagery with the 2.6-m Byurakan telescope. We studied...

The S254-258 star-forming complex is a place of massive star formation where five OB-stars have created HII regions, visible as optical nebulae, and disrupted the parental...

We here present the results from a detailed analysis of nebular abundances of commonly observed ions in the collisional ring galaxy Cartwheel using the Very Large Telescope...

To understand the nature of SiO emission, we conducted ACA observations of the SiO (2-1) lines toward 146 massive star-forming regions, as part of the ALMA Three-millimeter...

ATLASGAL is an 870um dust survey of 420deg^2^ the inner Galactic plane and has been used to identify ~10000 dense molecular clumps. Dedicated follow-up observations and...

Integral field units enable resolved studies of a large number of star-forming regions across entire nearby galaxies, providing insight on the conversion of gas into stars and...

We investigate radiation hardness within a representative sample of 67 nearby (0.02<~z<~0.06) star-forming (SF) galaxies using the integral field spectroscopic data from...

Polycyclic aromatic hydrocarbons (PAHs) are of great astrochemical and astrobiological interest due to their potential to form prebiotic molecules. We analyse the 7.7 and...

We present the KMOS Galaxy Evolution Survey (KGES), a K-band Multi-Object Spectrograph (KMOS) study of the H_{alpha} and [N II] emission from 288 K-band- selected galaxies at...

In the broad context of the Australian Square Kilometer Array Pathfinder (ASKAP) early-science phase and preparation for the related surveys, we report the first radio...

We present high spatial resolution (~= 12 pc) Atacama Large Millimeter/submillimeter Array 12CO(J = 3-2) observations of the nearby lenticular galaxy NGC 4429. We identify 217...

We have identified 453 compact dense cores in 3 mm continuum emission maps in the ALMA Three-millimetre Observations of Massive Star-forming regions survey, and compiled three...

We present independent determinations of cosmological parameters using the distance estimator based on the established correlation between the Balmer line luminosity,...

Supernovae (SNe) dominate the energy and momentum budget of stellar feedback, but the efficiency with which they couple to the interstellar medium (ISM) depends strongly on how...

We use a sample of 154 observations of 124 HII regions that have measurements of both T_e_[OIII] and T_e_[NII], compiled from the literature, to explore the behaviour of the...

IRAS 12272-6240 is a complex star-forming region with a compact massive dense clump (DC) and several associated masers, located at a well-determined distance of d=9.3kpc from...

Utilizing several instruments on 4-8m telescopes, we have observed a large sample of objects in the mid-infrared (8-13{mu}m). These comprise a few evolved stars, multiple...
