Ana Carolina Posses Nascimento<\/h2>\n\n\n\n

Postdoctoral Researcher at Texas A&M University<\/h4>\n\n\n\n

Former PhD student <\/h4>\n\n\n\n

I am currently a postdoctoral researcher at Texas A&M University. I graduated from UDP at the end of 2023. I work on galaxy evolution, particularly in the first half of universe’s history.<\/p>\n\n\n\n

Projects<\/h5>\n\n\n\n

I have been working on high-resolution observations of the [CII] emission in typical star-forming galaxies at z > 5, with ALMA. My work analyzing COS2987 (z = 6.8) has already been published and I am currently working with galaxy CRISTAL-5\/HZ3 (z = 5.5), analyzing the 3D cube from ALMA observations, and comparing with rest-frame-UV and near-infrared counterparts. These interesting study cases help me answer the following questions: What do the first galaxies look like? What physical mechanisms have shaped the structure and dynamics of these galaxies’ gaseous and dust components? What is the origin of the extended emission around these galaxies, known as [CII] halos? What is the dynamical state of early galaxies? This work aligns with the ALMA-CRISTAL survey, which is a census of the gas, dust, and stars in star-forming galaxies when the Universe was ~1 billion years old.<\/p>\n\n\n\n

Highlights<\/h5>\n\n\n\n

I am currently a member of the international collaboration of the ALMA Large Program CRISTAL ([CII] resolved ISM in star-forming galaxies with ALMA) survey.<\/p>\n\n\n\n
