Radio interferometric observations of candidate water-maser-emitting planetary nebulae
Jose F. Gomez, Olga Suarez, Yolanda Gomez +4
We present Very Large Array (VLA) observations of H2O and OH masers, as well as radio continuum emission at 1.3 and 18 cm toward three sources previously cataloged as planetary neb…
A sensitive survey for water maser emission towards Bok globules using the Robledo 70m antenna
Jose F. Gomez, Itziar de Gregorio-Monsalvo, Olga Suarez +1
We report the most sensitive water maser survey towards Bok globules to date, using NASA's 70m antenna in Robledo de Chavela (Spain). We observed 207 positions within the CB catalo…
CCS and NH3 emission associated with low-mass young stellar objects
I. de Gregorio-Monsalvo, J. F. Gomez, O. Suarez +3
In this work we present a sensitive and systematic single-dish survey of CCS emission (complemented with ammonia observations) at 1 cm, toward a sample of low- and intermediate-mas…
A disk of dust and molecular gas around a high-mass protostar
Nimesh A. Patel, Salvador Curiel, T. K. Sridharan +7
The processes leading to the birth of low-mass stars such as our Sun have been well studied, but the formation of high-mass (> 8 x Sun's mass) stars has heretofore remained poorly…
High-Resolution Molecular Line Observations of the Environment of the Class 0 Source B1-IRS
I. de Gregorio-Monsalvo, C. J. Chandler, J. F. Gomez +3
In this work we present VLA observations of the NH3, CCS, and H2O maser emission at 1 cm from the star forming region B1-IRS (IRAS 03301+3057) with ~ 5" (=1750 AU) of angular resol…
High-Resolution Observations in B1-IRS: ammonia, CCS and water masers
I. de Gregorio-Monsalvo, C. J. Chandler, J. F. Gomez +3
We present a study of the structure and dynamics of the star forming region B1-IRS (IRAS 03301+3057) using the properties of different molecules at high angular resolution (~4'').…
Molecular Line Emission from Accretion Disks Around YSOs
Itziar de Gregorio-Monsalvo, Jose F. Gomez, Paola D'Alessio
In this work we model the expected molecular emission from protoplanetary disks, modifying different physical parameters, such as dust grain size, mass accretion rate, viscosity, a…
A survey for water maser emission towards planetary nebulae. New detection in IRAS 17347-3139
Itziar de Gregorio-Monsalvo, Yolanda Gomez, Guillem Anglada +4
We report on a water maser survey towards a sample of 27 planetary nebulae (PNe) using the Robledo de Chavela and Medicina single-dish antennas, as well as the Very Large Array (VL…
Ammonia observations of the nearby molecular cloud MBM 12
Jose F. Gomez, Joaquin Trapero, Sergio Pascual +3
We present NH3(1,1) and NH3(2,2) observations of MBM 12, the closest known molecular cloud (65 pc distance), aimed to find evidence for on-going star formation processes. No local…
Resolving Molecular Line Emission from Protoplanetary Disks: Observational Prospects for Disks Irradiated by Infalling Envelopes
Jose F. Gomez, Paola D'Alessio
Molecular line observations that could resolve protoplanetary disks of ~100 AU both spatially and kinematically would be a useful tool to unambiguously identify these disks and to…
Evidence Against the Sciama Model of Radiative Decay of Massive Neutrinos
Stuart Bowyer, Eric J. Korpela, Jerry Edelstein +5
We report on spectral observations of the night sky in the band around 900 angstroms where the emission line in the Sciama model of radiatively decaying massive neutrinos would be…
