Thermal Radio Jets [PDF]

open access: yesSymposium - International Astronomical Union, 1997
Since thermal radio jets can be observed with subarsecond angular resolution and are unaffected by dust absorption, they provide a useful tool to study collimated outflows very close to the young stars that produce them. Here, I review recent results on this area, giving emphasis to the study of thermal jets in the case of the quadrupolar outflows in ...

Taking snapshots of the jet-ISM interplay with ALMA [PDF]

open access: yes, 2020
We present an update of our on-going project to characterise the impact of radio jets on the ISM by tracing molecular gas at high spatial resolution using ALMA. The radio active galactic nuclei (AGN) studied show recently born radio jets.

Scale-invariant radio jets and varying black hole spin [PDF]

open access: yes, 2016
Compact radio cores associated with relativistic jets are often observed in both active galactic nuclei and X-ray binaries. Their radiative properties follow some general scaling laws which primarily depend on their masses and accretion rates.

Discovery of synchrotron emission from a YSO jet

open access: yesEPJ Web of Conferences, 2013
Synchrotron emission at radio wavelengths is commonly found in relativistic jets from active galactic nuclei (AGNs) and microquasars and allows the study of the magnetic field in these kind of jets.

Powerful Jets from Radiatively Efficient Disks, a Decades-Old Unresolved Problem in High Energy Astrophysics

open access: yesGalaxies, 2021
The discovery of 3C 273 in 1963, and the emergence of the Kerr solution shortly thereafter, precipitated the current era in astrophysics focused on using black holes to explain active galactic nuclei (AGN).

Statistical multifrequency study of narrow-line Seyfert 1 galaxies [PDF]

open access: yes, 2014
High-energy {\gamma}-rays, which are produced by powerful relativistic jets, are usually associated with blazars and radio galaxies. In the current active galactic nuclei (AGN) paradigm, such jets are almost exclusively launched from massive elliptical ...

Jet-ISM Interaction in the Radio Galaxy 3C293: Jet-driven Shocks Heat ISM to Power X-ray and Molecular H2 emission [PDF]

open access: yes, 2015
We present a 70ks Chandra observation of the radio galaxy 3C293. This galaxy belongs to the class of molecular hydrogen emission galaxies (MOHEGs) that have very luminous emission from warm molecular hydrogen. In radio galaxies, the molecular gas appears

CORONAL JETS AS A CAUSE OF MICROWAVE NEGATIVE BURSTS

open access: yesSolar-Terrestrial Physics, 2020
We have investigated the cause of three “isolated” negative radio bursts recorded one after another at several frequencies in the 1–17 GHz range at the Nobeyama Radio Observatory, Ussuriysk Astrophysical Observatory, and Learmonth Solar Observatory on ...

Broadband VLA Spectral-line Survey of a Sample of Ionized Jet Candidates

open access: yesThe Astrophysical Journal Supplement Series, 2023
The study of the interaction between ionized jets, molecular outflows, and their environments is critical to understanding high-mass star formation, especially because jets and outflows are thought to be key in the transfer of angular momentum outward ...
