The Universality of Dark Matter Density Profiles for Milky Way Analog Galaxies
Maria Clara Cavalcante-Siviero, K. Menéndez-Delmestre, P. P. B. Beaklini +4
The structure, extent, and mass of the Milky Way's (MW) dark matter (DM) halo are observationally challenging to determine due to our position within the Galaxy. To overcome this l…
ALMA detection of Masers and Dasars in the Hydrogen Recombination Lines of the Planetary Nebula Mz3
Z. Abraham, P. P. B. Beaklini, I. Aleman +5
The hydrogen recombination lines H30, H40, H42, H50 and H57 and the underlying bremsstrahlung continuum emission were detected with ALMA in the bipolar nebula Mz3. T…
A two-component clumpy model for the shell evolution of classical novae: the case of V5668 Sgr
Zulema Abraham, Larissa Takeda, Pedro P. B. Beaklini +4
The shell of the classical nova V5668 Sgr was resolved by ALMA at the frequency of 230 GHz 927 days after eruption, showing that most of the continuum bremsstrahlung emission origi…
Dark matter distribution in Milky Way-analog galaxies
Natanael G. de Isídio, K. Menéndez-Delmestre, T. S. Gonçalves +9
Our current understanding of how dark matter (DM) is distributed within the Milky Way halo, particularly in the solar neighborhood, is based on either careful studies of the local…
Telluric absorption lines in the ALMA spectra of Car
Zulema Abraham, Pedro. P. B. Beaklini, Pierre Cox +2
The massive binary system formed by Car and an unknown companion is a strong source at millimetre and submillimetre wavelengths. Close to the stars, continuum bremsstrahlung an…
Sudden discharge of young charged magnetars as a new model for FRBs
Marcio G. B. de Avellar, Pedro P. B. Beaklini, Sílvia P. Nunes +2
We propose a new model for Fast Radio Bursts (FRBs) based on a sudden discharge of a charged young magnetar, caused by the short falling timescale of oppositely charged particles o…
Carinae: high angular resolution continuum, H30 and He30 ALMA images
Z. Abraham, P. P. B. Beaklini, P. Cox +2
We present images of Carinae in the recombination lines H30 and He30 and the underlying continuum with 50~mas resolution (110 AU), obtained with ALMA. For the first time,…
AGN dichotomy beyond radio loudness: a Gaussian Mixture Model analysis
Pedro P. B. Beaklini, Allan V. C. Quadros, Marcio G. B. de Avellar +2
Since the discovery of Quasi-stellar Objects (QSOs), also known as quasars, they have been traditionally subdivided as radio-loud and radio-quiet sources. Whether such division is…
Sulphur-Bearing and Complex Organic Molecules in an Infrared Cold Core
Pedro P. B. Beaklini, Edgar Mendoza, Carla M. Canelo +9
Since the start of ALMA observatory operation, new and important chemistry of infrared cold core was revealed. Molecular transitions at millimeter range are being used to identify…
Multiwavelength analysis of brightness variations of 3C~279: Probing the relativistic jet structure and its evolution
Pedro P. B. Beaklini, Tânia P. Dominici, Zulema Abraham +1
We studied the correlation between brightness and polarization variations in 3C~279 at different wavelengths, over time intervals long enough to cover the time lags due to opacity…
The structure of a recent nova shell as observed by ALMA
Marcos P. Diaz, Zulema Abraham, Valério A. R. M. Ribeiro +2
High resolution ALMA observations of the recent (2.52 yrs old) shell of Nova V5668 Sgr (2015) show a highly structured ionised gas distribution with small (10 cm) clumps. Th…
Herschel Planetary Nebula Survey (HerPlaNS): Hydrogen Recombination Laser Lines in Mz 3
Isabel Aleman, Katrina Exter, Toshiya Ueta +12
The bipolar nebula Menzel 3 (Mz 3) was observed as part of the \textit{Herschel} Planetary Nebula Survey (\textit{HerPlaNS}), which used the PACS and SPIRE instruments aboard the \…
Multiwavelength flaring activity of PKS1510-089
Pedro P. B. Beaklini, Tânia P. Dominici, Zulema Abraham
Aims: In this work, we analyse the multiwavelength brightness variations and flaring activity of FSRQ PKS1510-089, aiming to constrain the position of the emission sources. Methods…
Carinae Baby Homunculus Uncovered by ALMA
Zulema Abraham, Diego Falceta-Gonçalves, Pedro P. B. Beaklini
We report observations of Carinae obtained with ALMA in the continuum of 100, 230, 280 and 660 GHz in 2012 November, with a resolution that varied from 2.88" to 0.45" for the l…
3C273 variability at 7 mm: Evidences of shocks and precession in the jet
Pedro Paulo B. Beaklini, Zulema Abraham
We report 4 years of observations of 3C273 at 7 mm obtained with the Itapetinga Radiotelescope, in Brazil, between 2009 and 2013. We detected a flare in 2010 March, when the flux d…
SgrA* emission at 7mm: variability and periodicity
Pedro Paulo B. Beaklini, Zulema Abraham
We present the result of 6 years monitoring of SgrA*, radio source associated to the supermassive black hole at the centre of the Milky Way. Single dish observations were performed…
