ALMA observations of two massive and dense MALT90 clumps
Sudeep Neupane, Guido Garay, Yanett Contreras +2
We report Atacama Large Millimeter Array observations of 3 mm dust continuum emission and line emission, in HCO, HCO, NH and CHCN, towards two…
On the Effects of Self-Obscuration in the (Sub-)Millimeter Spectral Indices and Appearance of Protostellar Disks
Roberto Galván-Madrid, Hauyu Baobab Liu, Andrés F. Izquierdo +5
In this paper we explore the effects of self-obscuration in protostellar disks with a radially decreasing temperature gradient and a colder midplane. We are motivated by recent rep…
Resolving the Structure and Kinematics of the Youngest HII Regions and Radio Jets from Young Stellar Objects
Roberto Galván-Madrid, Maite Beltrán, Adam Ginsburg +4
In this contribution we explore the new science that a Next Generation Very Large Array (ngVLA) would be able to perform on the topics of the youngest HII regions and (proto)stella…
VLBA Observations of Strong Anisotripic Radio Scattering towards the Orion Nebula
Marina Kounkel, Lee Hartmann, Laurent Loinard +6
We present observations of VLBA 20, a radio source found towards the edge of the Orion Nebula Cluster (ONC). Nonthermal emission dominates the spectral energy distribution of this…
VLBA determination of the distance to nearby star-forming regions VII. Monoceros R2
Sergio A. Dzib, Gisela N. Ortiz-León, Laurent Loinard +4
We present a series of sixteen Very Long Baseline Array (VLBA) high angular resolution observations of a cluster of suspected low-mass young stars in the Monoceros R2 region. Four…
Pre- and Post-burst Radio Observations of the Class 0 Protostar HOPS 383 in Orion
Roberto Galván-Madrid, Luis F. Rodríguez, Hauyu B. Liu +5
There is increasing evidence that episodic accretion is a common phenomenon in Young Stellar Objects (YSOs). Recently, the source HOPS 383 in Orion was reported to have a $\times 3…
The Gould's Belt Distances Survey
Laurent Loinard
Very Long Baseline Interferometry (VLBI) observations can provide the position of compact radio sources with an accuracy of order 50 micro-arcseconds. This is sufficient to measure…
ALMA and VLA observations of recombination lines and continuum toward the Becklin-Neugebauer object in Orion
Roberto Galvan-Madrid, Ciriaco Goddi, Luis F. Rodriguez
Compared to their centimeter-wavelength counterparts, millimeter recombination lines (RLs) are intrinsically brighter and are free of pressure broadening. We report observations of…
High-resolution optical imaging of the core of the globular cluster M15 with FastCam
Anastasio Díaz-Sánchez, Antonio Pérez-Garrido, Isidro Villó +6
We present high-resolution I-band imaging of the core of the globular cluster M15 obtained at the 2.5 m Nordic Optical Telescope with FastCam, a low readout noise L3CCD based instr…
Radio continuum emission from knots in the DG Tau jet
L. F. Rodriguez, R. F. Gonzalez, A. C. Raga +5
Context: HH 158, the jet from the young star DG Tau, is one of the few sources of its type where jet knots have been detected at optical and X-ray wavelengths. Aims: To search, usi…
Millimeter multiplicity in DR21(OH): outflows, molecular cores and envelopes
Luis A. Zapata, Laurent Loinard, Y. -N. Su +4
We present sensitive high angular resolution ( 1) millimeter continuum and line observations from the massive star forming region DR21(OH) located in the Cygnus X molecula…
Disks and outflows in the massive protobinary system W3(OH)TW
Luis A. Zapata, Carolina Rodríguez-Garza, Luis F. Rodríguez +2
Sensitive and high angular resolution ( ) (sub)millimeter line and continuum observations of the massive star forming region W3(OH) made with the Submillimeter A…
A Cluster of Compact Radio Sources in W40
Luis F. Rodríguez, Steven A. Rodney, Bo Reipurth
We present deep 3.6 cm radio continuum observations of the HII region W40 obtained using the Very Large Array in its A and B configurations. We detect a total of 20 compact radio s…
From the Convergence of Filaments to Disk-Outflow Accretion: Massive-Star Formation in W33A
Roberto Galván-Madrid, Qizhou Zhang, Eric Keto +5
Interferometric observations of the W33A massive star-formation region, performed with the Submillimeter Array (SMA) and the Very Large Array (VLA) at resolutions from 5 arcsec (0.…
Formation of an O-Star Cluster by Hierarchical Accretion in G20.08-0.14 N
Roberto Galván-Madrid, Eric Keto, Qizhou Zhang +3
Spectral line and continuum observations of the ionized and molecular gas in G20.08-0.14 N explore the dynamics of accretion over a range of spatial scales in this massive star-for…
