    • A wide-angle outflow with the simultaneous presence of a high-velocity jet in the high-mass Cepheus A HW2 system 
      Torrelles, J. M.; Patel, N. A.; Curiel, S.; Estalella, R.; Gómez, J. F.; Rodríguez, L. F.; Cantó, J.; Anglada Escudé, Guillem; Vlemmings, W.; Garay Brignardello, Guido; Raga, A. C.; Ho, P. T. P. (2011)
      We present five epochs of VLBI water maser observations around the massive protostar Cepheus A HW2 with 0.4 mas (0.3 au) resolution. The main goal of these observations was to follow the evolution of the remarkable water ...
    • Evidence for evolution of the outflow collimation in very young stellar objects 
      Torrelles, J. M.; Patel, N. A.; Anglada Escudé, Guillem; Gómez, J. F.; Ho, P. T. P.; Lara, L.; Alberdi, A.; Cantó, J.; Curiel, S.; Garay Brignardello, Guido; Rodríguez, L. F. (2003-12-01)
      We present Very Long Baseline Array proper-motion measurements of water masers toward two young stellar objects (YSOs) of the W75 N star-forming region. We find that these two objects are remarkable for having a similar ...
    • Large proper motions in the jet of the high-mass YSO cepheus a HW2 
      Curiel, S.; Ho, P. T. P.; Patel, N. A.; Torrelles, J. M.; Rodríguez, L. F.; Trinidad, M. A.; Cantó, J.; Hernández, L.; Gómez, J. F.; Garay Brignardello, Guido; Anglada, G. (2006-02-20)
      Using high angular resolution ( 0B25–0B05) Very Large Array (VLA) observations made at 3.6 cm, 1.3 cm, and 7 mm during the period 1991–2004, we report the detection of large proper motions in the components of the ...
    • Spherical episodic ejection of material from a young star 
      Torrelles, J. M.; Patel, N. A.; Gómez, J. F.; Ho, P. T. P.; Rodríguez, L. F.; Anglada Escudé, Guillem; Garay Brignardello, Guido; Greenhill, L.; Curiel, S.; Cantó, J. (2001-05-17)
      The exact processes by which interstellar matter condenses to formyoung stars are of great interest, in part because they bear on the formation of planets like our own from the material that fails to become part of the ...
    • The circumstellar structure and excitation effects around the massive protostar Cepheus A HW 2 
      Torrelles, J. M.; Patel, N. A.; Curiel, S.; Ho, P. T. P.; Garay Brignardello, Guido; Rodríguez, Luis F. (2007)
      We report SMA 335 GHz continuum observations with angular resolution of similar to 0.3'', together with VLA ammonia observations with similar to 1'' resolution toward Cep A HW 2. We find that the flattened disk structure ...
    • The Nearby Evolved Stars Survey II: constructing a volume-limited sample and first results from the James ...

A.; Uttenthaler, S.; Ventura, P.; Wang, B.; Yamamura, I.; Yang, T.; Yun, Y.; Zhang, F.; Zhang, Y.; Zhao, G.; Zhu, M.; Zijlstra, A. A. (Oxford University Press, 2022)
      The Nearby Evolved Stars Survey (NESS) is a volume-complete sample of similar to 850 Galactic evolved stars within 3 kpc at (sub-)mm wavelengths, observed in the CO J = (2-1) and (3-2) rotational lines, and the sub-mm ...
