  • C/2014 Q2 (Lovejoy) spectra

    The presence of numerous complex organic molecules (COMs; defined as those containing 6 or more atoms) around protostars shows that star formation is accompanied by an increase...
  • Aminoacetonitrile transition frequencies

    Aminoacetonitrile, NH_2-CH_2_-CN, has been considered one of the important precursors of glycine, the simplest amino acid, and was identified in Sgr B2(N) by Belloche et al....
  • 350{mu}m molecular line survey of Orion KL

    With the Caltech Submillimeter Observatory, we have carried out an unbiased spectral line survey of Orion KL throughout the 350{mu}m band (from 795 to 903GHz). This is the first...
  • Radio observation of the transient CSS161010

    We present X-ray and radio observations of the Fast Blue Optical Transient CRTS-CSS161010J045834-081803 (CSS161010 hereafter) at t=69-531days. CSS161010 shows luminous X-ray...
  • CO in Protostars (COPS): Herschel spectroscopy

    We present full spectral scans from 200 to 670{mu}m of 26 Class 0+I protostellar sources obtained with Herschel-SPIRE as part of the "COPS-SPIRE" Open Time program,...
  • Rotational frequencies of TiO isotopologues

    Pure rotational spectra of the rare isotopologues of titanium oxide, ^46^TiO, ^47^TiO, ^49^TiO, and ^50^TiO, have been recorded using a combination of Fourier transform...
  • Rotational spectrum of vinyl formate (CH_2_=CHOCHO)

    Previous detections of methyl and ethyl formate make other small substituted formates potential candidates for observation in the interstellar medium. Among them, vinyl formate...
  • G358.93-0.03 6.67-23.12GHz CH3OH maser parameters

    We present the most complete to date interferometric study of the centimeter-wavelength methanol masers detected in G358.93-0.03 at the burst and post-burst epochs. A unique,...
  • 4 young protostars ALMA and NOEMA spectral cubes

    Water is a key volatile that provides insights into the initial stages of planet formation. However, little is known about the water vapor abundance in newly formed...
  • HCN-to-HNC intensity ratio

    The gas kinetic temperature (TK) determines the physical and chemical evolution of the interstellar medium (ISM). However, obtaining reliable TK estimates usually requires...
  • CO datacube and spectra of UGC 10214

    Minor mergers play a crucial role in galaxy evolution. UGC 10214 (the Tadpole galaxy) is a prime example of this process in which a dwarf galaxy has interacted with a large...
  • 1mm spectral line survey toward GLIMPSE EGOs

    A northern subsample of 89 Spitzer GLIMPSE extended green objects (EGOs), the candidate massive young stellar objects, are surveyed for molecular lines in two 1GHz ranges:...
  • methoxy radical (CH_3_O) rotational spectrum

    The methoxy radical (CH_3_O) has recently been detected in the interstellar medium and may be an important tracer of methanol-related chemistry in cold sources. Despite its...
  • DISCS. II. Southern sky disk data

    This is the second in a series of papers based on data from DISCS, a Submillimeter Array observing program aimed at spatially and spectrally resolving the chemical composition...
