My research is devoted to the study of the early stages of star formation in molecular clouds. Using different radioastronomical techniques at (sub-)mm wavelengths, I investigate the gas dynamics inside these objects and its connection with the formation of stars and dense cores. During the last years, I majored on the study of large-scale surveys of clouds, filaments, and cores combining both continuum and molecular line observations. Starting from the study of low-mass star-forming clouds like Taurus, I am extending now this work to more massive environments in regions like Orion or the more distant IRDCs.
Four main questions drive my research:
- Which physical processes control the formation of stars in molecular clouds?
- How does the transition between diffuse and dense gas occur inside clouds?
- What is the internal structure of low- and high-mass filaments?
- Is the star formation process universal?
- Streaming motions along filaments (Hacar & Tafalla 2011)
- Bundles of fibers in B213-L1495 (Hacar et al 2013)
- Stellar motions as fossil record of the gas kinematic structure (Hacar et al 2016)
- Evidence of fibers in the Orion Integral Filament (Hacar et al 2018)
- 3 Accepted ALMA Cycle 3, 4, & 6 proposals as PI (ALMA portal)
- PI of the ORION-4D project (link)
