What Do Radio Emission Constraints Tell Us About Little Red Dots as Tidal Disruption Events?
Krisztina Perger, Judit Fogasy, Sándor Frey
The real nature of little red dots (LRDs), a class of very compact galaxies in the early Universe recently discovered by the James Webb Space Telescope, is still poorly understood.…
Deep silence: radio properties of little red dots
K. Perger, J. Fogasy, S. Frey +1
To investigate the radio properties of the recently found high-redshift population, we collected a sample of little red dots (LRDs) from the literature. By cross-matching the…
Planetary radio interferometry and Doppler experiment as an operational component of the Jupiter Icy Moons Explorer mission
Vidhya Pallichadath, Dominic Dirkx, Marie S. Fayolle +9
We present an overview of the operations and engineering interface for Planetary Radio Interferometry and Doppler Experiment (PRIDE) radio astronomy observations as a scientific co…
Revisiting a Core-Jet Laboratory at High Redshift: Analysis of the Radio Jet in the Quasar PKS 2215+020 at z=3.572
Sándor Frey, Judit Fogasy, Krisztina Perger +4
The prominent radio quasar PKS 2215+020 (J2217+0220) was once labelled as a new laboratory for core--jet physics at redshift z=3.572 because of its exceptionally extended jet struc…
Milliarcsecond-scale radio structure of the most distant BL Lac object candidate at redshift 6.57
S. Frey, Y. Zhang, K. Perger +7
The existence of accreting supermassive black holes up to billions of solar masses at early cosmological epochs (in the context of this work, redshifts z>=6) requires very fast gro…
Planetary Radio Interferometry and Doppler Experiment (PRIDE) of the JUICE mission
Leonid I. Gurvits, Giuseppe Cimo, Dominic Dirkx +20
Planetary Radio Interferometry and Doppler Experiment (PRIDE) is a multi-purpose experimental technique aimed at enhancing the science return of planetary missions. The technique e…
VLA detects CO(1-0) emission in the z=3.65 quasar SDSS J160705+533558
Judit Fogasy, Kirsten K. Knudsen, Eskil Varenius
We present CO(1--0) observations of the high-redshift quasar SDSS J160705+533558 () using the Karl G. Jansky Very Large Array (VLA). We detect CO emission associated with…
ALMA detects molecular gas in the halo of the powerful radio galaxy TXS 0828+193
Judit Fogasy, Kirsten K. Knudsen, Guillaume Drouart +1
Both theoretical and observational results suggest that high-redshift radio galaxies (HzRGs) inhabit overdense regions of the universe and might be the progenitors of local, massiv…
SMM J04135+10277: A distant QSO-starburst system caught by ALMA
Judit Fogasy, Kirsten K. Knudsen, Guillaume Drouart +2
The gas content of galaxies is a key factor for their growth, starting from star formation and black hole accretion to galaxy mergers. Thus, characterising its properties via obser…
ALMA detections of CO emission in the most luminous, heavily dust-obscured quasars at z>3
Lulu Fan, Kirsten K. Knudsen, Judit Fogasy +1
We report the results of a pilot study of CO emission line of three {\it WISE}-selected hyper-luminous, dust-obscured quasars (QSOs) with sensitive ALMA Band 3 observations.…
Radio Jets Clearing theWay Through a Galaxy: Watching Feedback in Action in the Seyfert galaxy IC 5063
R. Morganti, T. A. Oosterloo, J. B. R. Oonk +2
High-resolution (0.5 arcsec) CO(2-1) observations performed with the Atacama Large Millimetre/submillimetre Array have been used to trace the kinematics of the molecular gas in the…
The first estimate of radio jet proper motion at z>5
S. Frey, Z. Paragi, J. O. Fogasy +1
The extremely high redshift (z=5.3) radio source SDSS J102623.61+254259.5 (J1026+2542) is among the most distant and most luminous radio-loud active galactic nuclei (AGN) known to…
Radio Jets Clearing the Way Through a Galaxy: Watching Feedback in Action
Raffaella Morganti, Judit Fogasy, Zsolt Paragi +2
The energy released by an active galactic nucleus (AGN) has a strong impact on the surrounding interstellar medium (ISM). This feedback is considered to be the regulating factor fo…
On the Doppler boosting in the compact radio jet of the distant blazar J1026+2542 at z=5.3
S. Frey, J. O. Fogasy, Z. Paragi +1
Based on its broad-band spectral energy distribution, and the X-ray spectrum in particular, the radio-loud active galactic nucleus (AGN) SDSS J102623.61+254259.5 (J1026+2542) has r…
