Revealing The CO X-factor In Dark Molecular Gas through Sensitive ALMA Absorption Observations
Gan Luo, Di Li, Ningyu Tang +11
Carbon-bearing molecules, particularly CO, have been widely used as tracers of molecular gas in the interstellar medium (ISM). In this work, we aim to study the properties of molec…
New search for mirror neutron regeneration
L. J. Broussard, K. M. Bailey, W. B. Bailey +18
The possibility of relatively fast neutron oscillations into a mirror neutron state is not excluded experimentally when a mirror magnetic field is considered. Direct searches for t…
Anisotropic Radio-Wave Scattering and the Interpretation of Solar Radio Emission Observations
Eduard P. Kontar, Xingyao Chen, Nicolina Chrysaphi +6
The observed properties (i.e., source size, source position, time duration, decay time) of solar radio emission produced through plasma processes near the local plasma frequency, a…
Space Telescope and Optical Reverberation Mapping Project. VIII. Time Variability of Emission and Absorption in NGC 5548 Based on Modeling the Ultraviolet Spectrum
G. A. Kriss, G. De Rosa, J. Ely +164
We model the ultraviolet spectra of the Seyfert 1 galaxy NGC~5548 obtained with the Hubble Space Telescope during the 6-month reverberation-mapping campaign in 2014. Our model of t…
Coronal Loop Scaling Laws for Various Forms of Parallel Heat Conduction
Stephen J. Bradshaw, A. Gordon Emslie, Nicolas H. Bian +1
The solar atmosphere is dominated by loops of magnetic flux which connect the multi-million-degree corona to the much cooler chromosphere. The temperature and density structure of…
The Green Bank North Celestial Cap Pulsar Survey. IV: Four New Timing Solutions
R. J. Aloisi, A. Cruz, L. Daniels +40
We present timing solutions for four pulsars discovered in the Green Bank Northern Celestial Cap (GBNCC) survey. All four pulsars are isolated with spin periods between 0.26s a…
