The Abundance of Clustered Primordial Black Holes from Quasar Microlensing
Sven Heydenreich, Evencio Mediavilla, Jorge Jiménez-Vicente +2
While elementary particles are the favored candidate for the elusive dark matter, primordial black holes (PBHs) have also been considered to fill that role. Gravitational microlens…
Using strong lensing to understand the microJy radio emission in two radio quiet quasars at redshift 1.7
P. Hartley, N. Jackson, S. Badole +3
The radio quasar luminosity function exhibits an upturn around W Hz that is well-modelled by a star-forming host galaxy population. This distribution…
VLA and ALMA observations of the lensed radio-quiet quasar SDSS J0924+0219: a molecular structure in a 3 microJy radio source
S. Badole, N. Jackson, P. Hartley +3
We present Karl G. Jansky Very Large Array (VLA) and Atacama Large Millimetre Array (ALMA) observations of SDSS J0924+0219, a z = 1.524 radio-quiet lensed quasar with an intrinsic…
ALMA images the many faces of the NGC1068 torus and its surroundings
S. Garcia-Burillo, F. Combes, C. Ramos Almeida +18
We investigate the fueling and the feedback of nuclear activity in the Seyfert 2 galaxy NGC1068, by studying the distribution and kinematics of molecular gas in the torus and its c…
Strong lensing reveals jets in a sub-microJy radio quiet quasar
P. Hartley, N. Jackson, D. Sluse +2
We present e-MERLIN and EVN observations which reveal unambiguous jet activity within radio quiet quasar HS~0810+2554. With an intrinsic flux density of 880~nJy, this is the fainte…
Limits on the Mass and Abundance of Primordial Black Holes from Quasar Gravitational Microlensing
E. Mediavilla, J. JimÉnez-Vicente, J. A. MuÑoz +2
The idea that dark matter can be made of intermediate-mass primordial black holes in the range has recently been reconsidered, particular…
Observations of the Lensed Quasar Q2237+0305 with CanariCam at GTC
H. Vives-Arias, J. A. Munoz, C. S. Kochanek +2
We present new mid-IR observations of the quadruply lensed quasar Q2237+0305 taken with CanariCam on the Gran Telescopio Canarias. Mid-IR emission by hot dust, unlike the optical a…
Structure of the Accretion Disk in the Lensed Quasar Q2237+0305 from Multi-Epoch and Multi-Wavelength Narrow Band Photometry
J. A. Munoz, H. Vives-Arias, A. M. Mosquera +3
We present estimates for the size and the logarithmic slope of the disk temperature profile of the lensed quasar Q2237+0305, independent of the component velocities. These estimate…
Observations of radio-quiet quasars at 10mas resolution by use of gravitational lensing
Neal Jackson, Amitpal S. Tagore, Carl Roberts +5
We present VLA detections of radio emission in four four-image gravitational lens systems with quasar sources: HS0810+2554, RXJ0911+0511, HE04351223 and SDSSJ0924+0219, and e-ME…
Outflows from AGN: Kinematics of the Narrow-Line and Coronal-Line Regions in Seyfert Galaxies
F. Müller-Sánchez, A. Prieto, E. K. S. Hicks +5
As part of an extensive study of the physical properties of active galactic nuclei (AGN) we report high spatial resolution near-IR integral-field spectroscopy of the narrow-line re…
