Seminario de Astrofísica en el IFIS. Este martes 20 de mayo, Constanza Norambuena, estudiante de Astronomía UC, presenta “The Effect of Massive Stellar Feedback Across the Carina Nebula Complex” desde las 14:30 horas en la Sala 208 del Instituto de Física PUCV, Campus Curauma.
Compartimos el abstract de la presentación:
Massive stars play a crucial role in affecting their surrounding environment, influencing star formation through radiative feedback. The Carina Nebula, located approximately 2.3 kpc away, serves as an excellent laboratory for studying these processes due to its large spatial extent and diverse star-forming environments.
In this project, we analyze ten selected regions within the nebula using ALMA Band 3 observations with the Atacama Compact Array and Total Power. Our focus is on molecular line emission (HCO⁺, HCN, CS) to investigate the physical and chemical conditions of the gas affected by massive stellar feedback.
This talk will focus on providing a brief overview of interferometry, the data processing steps, including imaging the interferometric observations using the tclean task in CASA, the combination of images from two different arrays (ACA 7-m and Total Power), and the various techniques that can be applied. Additionally, I will explain the generation of spectral cubes and the construction of moment maps to trace different gas structures.
Extendemos la invitación a la comunidad a participar de este seminario que busca aportar a la comprensión sobre las huellas que van dejando las estrellas masivas en su entorno interestelar.
