XPOL - the correlation polarimeter at the IRAM 30m telescope
Clemens Thum, Helmut Wiesemeyer, Gabriel Paubert +2
XPOL, the first correlation polarimeter at a large millimeter telescope, uses a flexible digital correlator to measure all four Stokes parameters simultaneously, i.e. the total pow…
Submillimeter pulsations from the magnetar XTE J1810-197
Pablo Torne, Graham Bell, Dan Bintley +13
We present the first detection of pulsations from a neutron star in the submillimeter range. The source is the magnetar XTE J1810-197, observed with the James Clerk Maxwell Telesco…
Searching for pulsars in the Galactic Centre at 3 and 2 mm
Pablo Torne, Gregory Desvignes, Ralph Eatough +13
Pulsars in the Galactic centre promise to enable unparalleled tests of gravity theories and black hole physics and to serve as probes of the stellar formation history and evolution…
A search for pulsars around Sgr A* in the first Event Horizon Telescope dataset
Pablo Torne, Kuo Liu, Ralph P. Eatough +282
The Event Horizon Telescope (EHT) observed in 2017 the supermassive black hole at the center of the Milky Way, Sagittarius A* (Sgr A*), at a frequency of 228.1 GHz (=1.3 mm). T…
POLAMI: Polarimetric Monitoring of Active Galactic Nuclei at Millimetre Wavelengths. I. The program, calibration, and calibrators data products
Ivan Agudo, Clemens Thum, Sol N. Molina +6
We describe the POLAMI program for the monitoring of all four Stokes parameters of a sample of bright radio-loud active galactic nuclei with the IRAM 30m telescope at 3.5 and 1.3mm…
Simultaneous Millimeter-wave and X-ray monitoring of the Seyfert Galaxy NGC 7469
Ehud Behar, Shai Kaspi, Gabriel Paubert +6
We report on daily monitoring of the Seyfert galaxy NGC 7469, around 95 GHz and 143 GHz, with the IRAM 30 m radio telescope, and with the Swift X-Ray and UV/Optical telescopes, ove…
