The Hercules-Aquila Cloud

open access: yes, 2007
We present evidence for a substantial overdensity of stars in the direction of the constellations of Hercules and Aquila. The Cloud is centered at a Galactic longitude of about 40 degrees and extends above and below the Galactic plane by at least 50 ...

Neutrino lighthouse at Sagittarius A*

open access: yesPhysical Review D, 2014
We investigate whether a subset of high-energy events observed by IceCube may be due to neutrinos from Sagittarius A*. We check both spatial and temporal coincidences of IceCube events with other transient activities of Sagittarius A*. Among the seven IceCube shower events nearest to the galactic center, we have found that event 25 has a time very ...

HI Observations Towards the Sagittarius Dwarf Spheroidal Galaxy [PDF]

open access: yes, 1999
We have measured the 21-cm line of Galactic HI over more than 50 square degrees in the direction of the Sagittarius dwarf spheroidal galaxy. The data show no evidence of HI associated with the dwarf spheroidal which might be consider analogous to the ...

On the Spiral Structure of the Milky Way Galaxy

open access: yes, 2010
We consider the possible pattern of the overall spiral structure of the Galaxy, using data on the distribution of neutral (atomic), molecular, and ionized hydrogen, on the base of the hypothesis of the spiral structure being symmetric, i.e.

Galactic substructure traced by RR Lyraes in SDSS Stripe 82

open access: yesEPJ Web of Conferences, 2012
Using a sample of 407 RR Lyrae stars extracted from SDSS Stripe 82, we study the degree of substructure in the Galactic halo. We identify overdensities associated with the known substructures of the Hercules-Aquila Cloud and the Sagittarius Stream, and ...

On the HI-Hole and AGB Stellar Population of the Sagittarius Dwarf Irregular Galaxy

open access: yes, 2014
Using two HST/ACS data-sets that are separated by ~2 years has allowed us to derive the relative proper-motion for the Sagittarius dwarf irregular (SagDIG) and reduce the heavy foreground Galactic contamination.

The Core Mass Function across Galactic Environments. IV. The Galactic Center

open access: yesThe Astrophysical Journal
The origin of the stellar initial mass function (IMF) and how it may vary with galactic environment is a matter of debate. Certain star formation theories involve a close connection between the IMF and the core mass function (CMF), so it is important to ...

Herpetofauna of Katerniaghat Wildlife Sanctuary, Uttar Pradesh, India

open access: yesJournal of Threatened Taxa, 2012
A herpetofaunal inventory based on field surveys, literature records and photographic records is presented for Katerniaghat Wildlife Sanctuary and its environs, situated in the Terai region of Uttar Pradesh, India.

An Inward-moving and Asymmetric Velocity Wave Detected in LAMOST-Gaia

open access: yesThe Astrophysical Journal Letters
The phase space, as coded by kinematic parameters and chemical abundances, is crucial for understanding the formation of the Galactic disk. Using red giant stars from the Galactic thin disk with [Fe/H] > − 0.8 and low- α ratios identified in LAMOST-Gaia,
