We used deep Gemini-South/GMOS g ^ { \prime } r ^ { \prime } i ^ { \prime } z ^ { \prime } images to study the globular cluster ( GC ) system of the massive elliptical galaxy NGC 1395 , located in the Eridanus supergroup .
The photometric analysis of the GC candidates reveals a clear colour bimodality distribution , indicating the presence of “ blue ” and “ red ” GC subpopulations .
While a negative radial colour gradient is detected in the projected spatial distribution of the red GCs , the blue GCs display a shallow colour gradient .
The blue GCs also display a remarkable shallow and extended surface density profile , suggesting a significant accretion of low-mass satellites in the outer halo of the galaxy .
In addition , the slope of the projected spatial distribution of the blue GCs in the outer regions of the galaxy , is similar to that of the X-ray halo emission .
Integrating up to 165 kpc the profile of the projected spatial distribution of the GCs , we estimated a total GC population and specific frequency of 6000 \pm 1100 and S _ { N } =7.4 \pm 1.4 , respectively .
Regarding NGC 1395 itself , the analysis of the deep Gemini/GMOS images shows a low surface brightness umbrella-like structure indicating , at least , one recent merger event .
Through relations recently published in the literature , we obtained global parameters , such as M _ { \mathrm { stellar } } = 9.32 \times 10 ^ { 11 } M \odot and M _ { h } = 6.46 \times 10 ^ { 13 } M \odot .
Using public spectroscopic data , we derive stellar population parameters of the central region of the galaxy by the full spectral fitting technique .
We have found that , this region , seems to be dominated for an old stellar population , in contrast to findings of young stellar populations from the literature .
