An ALMA view on molecular complexity: water, methanol, and methyl formate in the HD 100546 and IRS 48 disks
Luna Rampinelli, Stefano Facchini, Marta De Simone +6
Water and methanol are the fundamental constituents of interstellar and cometary ices: understanding their abundances in disks is therefore of high importance to reveal how this ic…
High-frequency water megamasers as precision probes of black holes, galaxies and cosmology: A case for a next-generation sub-mm/mm interferometer
Ingyin Zaw, C. M. Violette Impellizzeri, Dominic W. Pesce +8
Water megamasers in the circumnuclear disks of active galactic nuclei are among the most precise probes of supermassive black holes. VLBI imaging of 22 GHz disk masers has provided…
Into the thick of it: ALMA 0.45 mm observations of HL Tau at 2 au resolution
Osmar M. Guerra-Alvarado, Carlos Carrasco-González, Enrique Macías +7
Aims. To comprehend the efficiency of dust evolution within protoplanetary disks, it is crucial to conduct studies of these disks using high-resolution observations at multiple wav…
Resolved ALMA observations of water in the inner astronomical units of the HL Tau disk
Stefano Facchini, Leonardo Testi, Elizabeth Humphreys +7
The water molecule is a key ingredient in the formation of planetary systems, with the water snowline being a favourable location for the growth of massive planetary cores. Here we…
Sub-Parsec-Scale Jet-Driven Water Maser with Possible Gravitational Acceleration in the Radio Galaxy NGC 1052
Seiji Kameno, Yuichi Harikane, Satoko Sawada-Satoh +5
We report sub-pc-scale observations of the 321-GHz HO emission line in the radio galaxy NGC 1052. The HO line emitter size is constrained in milliarcsec distributed…
ALMA High-frequency Long Baseline Campaign in 2021: Highest Angular Resolution Submillimeter Wave Images for the Carbon-rich Star R Lep
Yoshiharu Asaki, Luke T. Maud, Harold Francke +11
The Atacama Large Millimeter/submillimeter Array (ALMA) was used in 2021 to image the carbon-rich evolved star R Lep in Bands 8-10 (397-908 GHz) with baselines up to 16 km. The goa…
A search for signatures of interactions of X-ray binary outflows with their environments with ALMA
M. Díaz Trigo, D. Petry, E. Humphreys +2
We observed the X-ray binaries CirX-1, ScoX-1, GRS 1915+105, GX13+1, and CygX-1 with the Atacama Large Millimeter/submillimeter Array (ALMA). Unresolved continuum emission is found…
Magnetically aligned dust and SiO maser polarization in the envelope of the red supergiant VY CMa
W. H. T. Vlemmings, T. Khouri, I. Marti-Vidal +9
We use Atacama Large Millimeter/submillimeter Array Band 5 science verification observations of the red supergiant VY CMa to study the polarization of SiO thermal/masers lines and…
Simultaneous 183 GHz H2O Maser and SiO Observations Towards Evolved Stars Using APEX SEPIA Band 5
E. M. L. Humphreys, K. Immer, M. D. Gray +10
We investigate the use of 183 GHz H2O masers for characterization of the physical conditions and mass loss process in the circumstellar envelopes of evolved stars. We used APEX SEP…
The Physics of Water Masers observable with ALMA and SOFIA: Model Predictions for Evolved Stars
M. D. Gray, A. Baudry, A. M. S. Richards +3
We present the results of models that were designed to study all possible water maser transitions in the frequency range 0-1.91THz, with particular emphasis on maser transitions th…
ALMA observations of TiO around VY Canis Majoris
E. De Beck, W. Vlemmings, S. Muller +7
Titanium dioxide, TiO, is a refractory species that could play a crucial role in the dust-condensation sequence around oxygen-rich evolved stars. To date, gas phase TiO has…
