Multi-band optical photometric variability of the blazar OJ 287 from 2015 to 2025
Alok C. Gupta, Karan Dogra, Mark Kidger +101
We present the most densely sampled multi-band optical photometric observations of the peculiar BL Lacertae object OJ 287 from 2015 to 2025 with a focus on its optical activity on…
Detailed lens modeling and kinematics of the submillimeter galaxy G09v1.97. An analysis of CO, H2O, H2O+, and dust continuum emission
K. Kade, C. Yang, M. Yttergren +14
The formation mechanisms of intensely starbursting galaxies at high redshift remain unknown. One possible mechanism for triggering these starbursts is mergers and interactions, but…
A study of Intrinsic -ray Emission for {\it Fermi}/LAT-detected BL Lacs
X. H. Ye, X. T. Zeng, W. X. Yang +7
BL Lacs are one subclass of blazars with highly energetic -ray emission, which is strongly boosted by a relativistic beaming effect. The latest catalogue of the 10 years of {\it…
A new MWA limit on the 21 cm Power Spectrum at Redshifts 13 17
S. Yoshiura, B. Pindor, J. L. B. Line +29
Observations in the lowest MWA band between MHz have the potential to constrain the distribution of neutral hydrogen in the intergalactic medium at redshift .…
The unusual ISM in Blue and Dusty Gas Rich Galaxies (BADGRS)
L. Dunne, Z. Zhang, P. de Vis +12
The Herschel-ATLAS unbiased survey of cold dust in the local Universe is dominated by a surprising population of very blue (FUV-K < 3.5), dust-rich galaxies with high gas fractions…
The ever-surprising blazar OJ 287: multi-wavelength study and appearance of a new component in X-rays
Pankaj Kushwaha, Alok C. Gupta, Paul J. Wiita +21
We present a multi-wavelength spectral and temporal investigation of OJ 287 emission during its strong optical-to-X-ray activity between July 2016 - July 2017. The daily -ray fl…
Characterizing optical variability of OJ 287 in 2016 - 2017
Alok C. Gupta, Haritma Gaur, Paul J. Wiita +22
We report on a recent multi-band optical photometric and polarimetric observational campaign of the blazar OJ 287 which was carried out during September 2016 -- December 2017. We e…
Multi-wavelength temporal and spectral variability of the blazar OJ 287 during and after the December 2015 flare: a major accretion disc contribution
P. Kushwaha, A. C. Gupta, P. J. Wiita +33
We present a multi-wavelength spectral and temporal analysis of the blazar OJ 287 during its recent activity between December 2015 -- May 2016, showing strong variability in the ne…
The most distant, luminous, dusty star-forming galaxies: redshifts from NOEMA and ALMA spectral scans
Y. Fudamoto, R. J. Ivison, I. Oteo +23
We present 1.3- and/or 3-mm continuum images and 3-mm spectral scans, obtained using NOEMA and ALMA, of 21 distant, dusty, star-forming galaxies (DSFGs). Our sample is a subset of…
Multiband optical variability of the blazar OJ 287 during its outbursts in 2015 -- 2016
Alok C. Gupta, A. Agarwal, A. Mishra +31
We present recent optical photometric observations of the blazar OJ 287 taken during September 2015 -- May 2016. Our intense observations of the blazar started in November 2015 and…
