The counterjet dominates the production of PeV photons from Cyg X-3
Andrzej A. Zdziarski, Anton Dmytriiev, Karri I. I. Koljonen
We study the physical mechanisms underlying the production of orbitally-modulated PeV photons from Cyg X-3, recently discovered by the LHAASO collaboration. Our key findings are as…
Association of the IceCube neutrinos with CAZ blazar light curves
Pouya M. Kouch, Talvikki Hovatta, Elina Lindfors +3
The IceCube Neutrino Observatory has detected several hundred high-energy neutrinos from cosmic sources. Despite numerous studies searching for their origin, it is still not known…
CAZ catalog and optical light curves of 7918 blazar-selected active galactic nuclei
Pouya M. Kouch, Elina Lindfors, Talvikki Hovatta +10
Active galactic nuclei (AGN) are some of the brightest and most variable objects in the Universe. Those with relativistic jets observed at small viewing angles are blazars. Due to…
Towards ALMA2040: An update from the European community and invitation to contribute
Stefano Facchini, Jacqueline Hodge, Jes Jørgensen +27
Over the last 15 years, the Atacama Large Millimeter/submillimeter Array (ALMA) has revolutionized astrophysics by providing unprecedented resolution and sensitivity in observing t…
COBIPLANE: A Systematic Search for Compact Binary Millisecond Pulsars at Low Galactic Latitudes
Marco Turchetta, Manuel Linares, Karri Koljonen +2
We present the main results obtained from the COmpact BInary Pulsar search in the low-LAtitude NEighborhood (COBIPLANE), an optical photometric survey designed to find new `spider'…
Serendipitous and targeted mm/sub-mm transient searches with wide-FOV telescope
Karri Koljonen, Claudio Ricci, Thomas Stanke +4
The millimeter/sub-millimeter (mm/sub-mm) sky remains a rich but under-explored frontier for transient and variable phenomena. A wide-field, high-sensitivity instrument with a larg…
