Black holes are famous for their muscle: an intense gravitational pull known to gobble up entire stars and launch streams of matter into space at almost the speed of light.It turns out the reality may...
Baker & Vinokurova (2010) argue that the distribution of morphologically observable case
in Sakha (Turkic) requires a hybrid account, which involves recourse both to congurational
rules of cas...
Spatial Variability of Groundwater Recharge - I. Is it really variable?
Spatial variability Groundwater recharge Sri Lanka
2015/8/6
The spatial variability of recharge is an important consideration in estimating recharge especially as all methods of estimating it are 'point' estimates and in most places recharge varies in space. T...

Do Fermi-LAT observations really imply very large Lorentz factors in GRB outflows ?
gamma-ray burst: general gamma-ray burst: individual: GRB 080916C radiative transfer radiation mechanisms: non-thermal
2011/10/20
Recent detections of GeV photons in a few GRBs by Fermi-LAT imply huge bulk Lorentz factors to avoid a large gamma gamma optical depth at high energy. Estimates can be as high as Gamma ~ 1000 in the m...
Abstract: The Hubble law, determined from the distance modulii and redshifts of galaxies, for the past 80 years, has been used as strong evidence for an expanding universe. This claim is reviewed in l...
Are two resources really better than one? Some unexpected results of the availability of substitutes
resources unexpected results of the availability of substitutes
2011/1/5
The possibility of exploiting multiple resources is usually regarded as positive from both the economic and the environmental point of view. However, resource switching may also lead to unsustainable ...
Is Palomar 1 really associated with the Canis Major overdensity?
Palomar Canis Major overdensity
2010/11/16
t has recently been suggested that the peculiar cluster Pal 1 is associated to the Canis Major dwarf galaxy, which existence is still at the center of a debate. Our rst measurement of the cluster's c...
Thermohaline Mixing: Does It Really Govern the Atmospheric Chemical Composition of Low-Mass Red Giants?
stars abundances — stars evolution — stars interiors
2010/11/12
First results of our 3D numerical simulations of thermohaline convection driven by 3He burning in a low-mass RGB star at the bump luminosity are presented. They confirm our previous conclusion that th...
Have Baryonic Acoustic Oscillations in the galaxy distribution really been measured?
galaxies: statistics cosmology theory large-scale structure
2010/11/15
Recent publications claim that there is no convincing evidence for measurements of the baryonic acoustic (BAO) feature in galaxy samples using either monopole or radial information. Di erent claims se...
Can Maxwell's Fish Eye Lens Really Give Perfect Imaging? Part II. The case with drains
Maxwell's Fish Eye Lens Perfect Imaging Part II
2010/11/16
We use both FEM (finite element method) and FDTD (finite difference time domain method) to simulate the field distribution in Maxwell's fish eye lens with one or more passive drains around the image ...
