[AAA] Viernes 6 de agosto 10hs: Tercer encuentro del Ciclo de Seminarios LLAMA en homenaje a Cristina Cappa

[Silvina Cichowolski]

Estimadas y estimados colegas,

Nos ponemos en contacto con ustedes
para invitarlas/os al tercer encuentro del Ciclo de Seminarios que
estamos organizando para que las comunidades astronómicas de Argentina y
Brasil empiecen a tomar contacto con el proyecto LLAMA.
Este ciclo tiene lugar los primeros viernes de cada mes, de 10 a 12 hs, en
formato
virtual.
Cada encuentro consiste de 3 charlas invitadas (la primera de
40 minutos de duración y las otras dos de 20 minutos cada una) e
intervalos para discusiones.

Este encuentro se realizará en homenaje a nuestra querida compañera y
amiga Prof. Dra. Cristina Cappa.

La participación online en
los seminarios se realizará a través de la plataforma Zoom.

Posteriormente, las presentaciones se ponen a disposición en el canal
de LLAMA en YouTube:

EL PRÓXIMO ENCUENTRO SERÁ EL VIERNES 6 DE AGOSTO DE 2021, CON EL SIGUIENTE
CRONOGRAMA:


10hs: Lars-Ake Nyman (European Southern Observatory)

 "My experience in installation, commissioning and operations of radio
telescopes at high altitude"

Abstract:
I will present my experience in installing and operating telescopes at
high altitudes.
This is mainly based on my work at APEX, where I was the Station Manager
during installation, commissioning and first operations.


11hs: Pedro P.B. Beaklini (NRAO)

 "Monitoring blazar variability at radio (sub)millimeter wavelengths"

Abstract:
Blazars are high luminosity AGNs presenting relativistic jets seen at
small angles to the line of sight. They are also characterized by
variability across the entire electromagnetic spectrum, and the emission
is boosted due to relativistic effects. In this talk, I will present
observations carried out at 43 GHz (7 mm) for the blazars 3C 273, 3C 279,
and PKS 1510-089 using the Pierre Kaufmann Radio Observatory (former
Itapetinga, Atibaia, Brazil). First, I will report the variability
monitoring results of these sources and how they correlate with other
wavelengths, like optical and gamma-ray. Following the mm results, I will
show a high-frequency follow-up of the blazar monitoring program to use
the LLAMA (Large Latin America Millimeter Array). There are a few data of
submillimeter variability information in the literature, most of them
obtained during the SEST era (Swedish-ESO Submillimetre Telescope), and
LLAMA will provide crucial information to understand about blazar physics.


11:30hs: Isabel Aleman (Universidade Federal de Itajubá – UNIFEI, Brazil)

 "Molecules in Planetary Nebula: LLAMA and the Chemistry in Harsh
Environments"

Abstract: Planetary nebulae are excellent “laboratories” for the study of
many topics, such as stellar evolution, mass loss, cosmic abundances, the
life cycle of gas and dust in a galaxy, and Astrochemistry. Recent
observations made with Herschel, Spitzer, and other instruments revealed
that PNe have a rich and still not well understood chemistry.
With the eminent opening of Large Latin American Millimeter Array’s
(LLAMA) eyes to the sky, we have an excellent opportunity.
Observations of molecules in the submillimeter spectral range, where many
molecules emit lines, offer a particularly interesting and still
not very explored tool for the study of astrophysics and astrochemistry in
PNe. In this talk, I will discuss how LLAMA may have
an important role in such studies
